ASG STI Duty One

The ASG STI Duty One is a fairly typical product from Danish distributor ASG – it’s well made, well finished and a good replica of the original pistol.  However, it does have a couple of idiosyncrasies which you need to bear in mind if you’re thinking of buying one.

ASG produce two replicas based on the STI Duty One – one has blowback and one doesn’t.  Apart from blowback, the two appear to be identical (though the non-blowback version is a little cheaper to buy). The ASG STI Duty One is also available in both 6mm and 4.5mm form. I have owned three examples of this replica and all were 4.5mm, blowback versions, so that’s what I’ll mainly be talking about here.

Real steel background

In the early 1990s, Texan gunsmith Virgil Tripp started building custom 1911 pistols for the growing IPSC market.  His attention to detail and the quality of his products quickly brought commercial success and in 1993 a young engineer and Computer Aided Design (CAD) specialist called Sandy Strayer joined Tripp Research Inc.  With Tripp’s pistol knowledge and Stayer’s engineering skills, the two revolutionised the 1911 market when they introduced the 2011 range in 1994.  This provided a modular frame using fiber-reinforced plastic for the trigger guard, grip, and magazine well which was attached to the metal upper portion of the frame.  The STI 2011 frame was strong and reliable but less than half the weight of a conventional all-metal 1911 frame.

One of the STI International 2011 range

The company changed its name to Strayer-Tripp, Inc. (STI) in 1994 and focused on two distinct lines of pistol – the 1911 range which provided pistols with a conventional frame based on the 1911 design and the 2011 range which used the new modular frame.  In 1997 the company was bought over by the owners of electronics company Tessco, Inc., and was re-named STI International.  The STI 1911 and 2011 ranges continued to be popular and by 2007 STI International was the third largest exporter of guns in the USA.

The STI International Duty One

The Duty One is one of the most popular pistols in the STI International 1911 range.  However, unlike many STI pistols, this isn’t primarily intended as a target shooter.  It’s a practical carry gun with fixed sights which is available with 3″, 4″ and 5″ barrels and chambered either for the .45 ACP round or the 9x19mm.  The Duty One features a patented STI International lightweight trigger and a commander style hammer and is supplied with a distinctive matte blued finish.  An ambidextrous thumb safety is provided in addition to the grip safety.  The Duty One is available in standard and “lite” form, which incorporates a lightweight aluminium frame.  The Duty One was redesigned in 2014 and current versions feature a distinctive “grid” pattern slide grip serrations and a revised grip.

The ASG STI Duty One

The ASG STI Duty One is a licensed replica of mostly metal construction with a stick type drop-out magazine and a short under-barrel accessory rail.  CO2 is retained inside the grip and accessed by removing the backstrap and grip base.  This replica is manufactured in Taiwan on behalf of ASG and is available in 4.5mm and 6mm.  ASG produce two versions of the STI Duty One – one with blowback and one without.  The figures below and the information in this article is based on my experience with the blowback version.  The non-blowback version looks very similar, but I haven’t tried it.  I believe that the 4.5mm version is available in matte black finish only though there is a two-tone version of the non-blowback and the 6mm blowback versions with a polished slide.  All versions include full STI markings.

Two-tone 6mm version

The slide moves through less than the full range of travel during blowback and locks back when the last round is fired.  The thumb safety, magazine and slide release work as per the original but the grip safety is moulded in place and has no function.  The ASG STI Duty One cannot be field stripped, but ASG do provide dismantling instructions on their website (you’ll find a link at the end of this article).  ASG also produce CO2 powered replicas of several other STI handguns including the Lawman, Tac Master, Combat Master and the tiny Off Duty.

Packaging and presentation  2.5/5

The ASG STI Duty One is provided in a card box with a single magazine and a short user manual.

Visual accuracy  8/10

The ASG STI Duty One is generally a good visual replica of the pre-2014 STI Duty One.  Grips, markings, finish and overall shape and profile are very good indeed and all controls are a good visual match for the original.  The main visual difference is the trigger – the ASG replica uses a pivoting style trigger rather than the sliding 1911 style trigger seen on the original.

Functional accuracy  11/15

The version tested is a blowback replica with a drop-out, stick-type magazine.  The trigger operates in single action only and the slide locks back after the last round is fired.  The slide catch, magazine release and thumb safety work as per the original weapon.  The slide moves through restricted travel compared to the cartridge version.  The grip safety is moulded in place and has no function.

The slide release catch on the cartridge version can be extracted to the left side to allow the slide to be removed.  On this version the slide release cannot be extracted and the slide cannot be removed.

Shooting  30/40

The CO2 chamber is accessed by pressing a button in the base of the grip, which allows the plastic panel which forms base and rear of the grip to be removed.  CO2 can then be inserted and tightened and pierced using the plastic tab at the base of the grip.  The tightening tab is a little small and quite fiddly for use with large man-fingers, but with a bit of practise this can be done without too much drama.  It can sometimes be difficult to remove the used CO2 cartridge.  Even with the cover plate removed and the tab loosened as much as possible, it can take a fair bit of shaking to get the CO2 to drop out.  Re-fitting the cover panel can also be a little fiddly, though it’s nice to see that this completely conceals the loading tab once it’s in place.

Loading the stick type magazine reveals the first of this replicas’ idiosyncrasies.  The follower locks down, which makes it easy to load BBs in to the port at the top of the magazine.  However, if you then release the follower, the BBs will spray back out of top of the magazine.  To prevent this, you must cover the holes at the front and rear of the top of the magazine with your fingers as you release the follower.

When you have CO2 and BBs loaded, the ASG STI Duty One feels good.  The chunky, deeply serrated rubberised grips and angular frame allow a firm and consistent grip.  STI International obviously knows a great deal about how to make a handgun that handles well, and the ASG version replicates this nicely.  This feeling is reinforced when you pull the trigger – a loud bang and very strong blowback make this feel like a powerful and purposeful shooter.

However, pulling the trigger also reveals the second odd issue with this pistol.  Like many blowback replicas, the blowback action cocks the hammer, but it doesn’t queue the next BB for shooting.  This is done during the long first part of the trigger pull, and the movement of the BB can clearly be felt.  The problem here is that if you pull the trigger fairly slowly towards the release point, the BB can roll out of the front of the barrel if the pistol is pointed level or slightly down.  The solution is to pull the trigger firmly and fairly quickly (the manual actually warns that the trigger should be pulled “in one swift motion“), but this doesn’t help with accuracy.  This issue does seem to be variable – on one of my Duty Ones, BBs regularly fell out of the end of the barrel before I was ready to shoot, but the other two seemed less prone to this.  And if for any reason you pull the trigger back and then release it without firing, when you next pull the trigger you will load a second BB into the breech and you’ll then fire both at once.  The trigger action on this pistol is a problem and it’s notably worse than, for example, the ASG CZ75 (though it’s identical to the trigger on the ASG CZ P-07 Duty, which has the same fault).  You really must develop a style where you pull the trigger quickly and confidently every time if you are to avoid issues.  Being tentative will lead to double loading or losing the BB before you shoot.

The loud bang and strong blowback make the Duty One feel powerful, but the numbers don’t really back this up.  I have owned three 4.5mm examples of the ASG STI Duty One and all chronoed at around 325 – 350 fps dependent on temperature.  Perfectly respectable figures, but well short of the 436fps claimed by ASG.  Accuracy was also average without being great.  Even though they lack white dots, the sights are clear and easy to read but grouping with two of my Duty Ones was around 1½” – 2″ at six yards – fair but not great.  The third example was notably worse, grouping at 2″ – 3″ at six yards.  These aren’t terrible figures, so perhaps it’s just because the ASG Duty One feels like it’s so powerful and accurate that they seem a little disappointing?

CO2 consumption is fair for a blowback replica with three magazines (60 shots) of full-power shots available from a single CO2.  If you continue to a fourth magazine, you’ll gradually run out of puff until the CO2 is completely exhausted somewhere around the 70th shot.

Other than the issues noted, the ASG STI Duty One appears to be reliable.  The slide locks back every time and I had no mechanical problems or failures with any of the examples I owned.  Because the slide and magazine releases and the thumb safety are on the left side only, this isn’t a particularly great pistol if you’re left-handed.

Quality and reliability  13/15

The overall fit and finish of the ASG STI Duty One are very good indeed.  Everything fits well without rattles or movement and seams are well finished. The rubberised grips are a particularly nice touch and the matte black finish seems more durable than the finish on many replicas (which sadly isn’t difficult).  I have heard of owners who have had the front sight come loose on this model, though I didn’t experience this on any of mine.

The operational issues noted in the Shooting section seem to be design flaws rather than manufacturing defects, and this does seem to be generally a high quality replica which is available at a very reasonable price.

Overall Impression  11/15

This is a great looking, well made and well finished replica but for me, trigger action is at the heart of how much I enjoy shooting a pistol.  On the ASG Duty One, the trigger action is flawed, which I found very frustrating.  This replica looks good and feels great, but the shooting experience just doesn’t deliver what is promised.  I ended up buying three different Duty Ones, in the hope that I’d find one which shot as well as it looked and handled.  I failed, and I’m not sure that I’d buy another.

Conclusion

I’m a big fan of the 1911 platform and I generally like updated 1911s.  In some ways this is a good replica of a modernised 1911.  It’s certainly a good looking and well made pistol.  However, I found its shooting ability to be poor and the trigger action disappointing.  And after all, the ability to shoot is the reason we buy this type of replica rather than a non-shooting wall ornament.

If you can find one that shoots well, or if you’re willing and able to modify your shooting technique to overcome its inherent issues, you may enjoy the ASG STI Duty One.  If not, there are probably better ASG products and better 1911 replicas to add to your collection.

Pros

Very nice looking replica

Feels solid and well made

Finish seems to be more durable than average

Strong blowback

Cons

Trigger action

Accuracy and power aren’t all that great

Non-working grip safety

Not lefty friendly

Guide to dismantling the STI Duty One provided by ASG

ASG CZ 75

I’m rarely surprised by replicas.  I have owned a fair number and I generally have a good idea of what to expect before I even pick a new replica up.  But occasionally I find something unexpected in a pistol and that happened recently when I was provided with an ASG CZ 75 for review.

I have owned several ASG replicas, and they’re generally pretty good.  In terms of blowback, semi-auto BB shooters, I have owned an STI Duty One and a CZ P-07 Duty.  Both were very nicely made and finished, powerful, reliable and reasonably accurate, but I didn’t especially care for the trigger action on either – like many replicas they both use the first part of the single action trigger pull to queue up the next BB for shooting and neither could be field stripped.  Not show-stopping issues to be sure, but I do like functional accuracy and a true single action trigger.  I assumed (always a dangerous thing to do) that the ASG CZ 75 would be similar.  How wrong I was…

Real steel background

State-owned arms manufacturer Česká zbrojovka Uherský Brod (CZUB) was established in 1936 in the small town of Uherský Brod in what was then Czechoslovakia and is now the Czech Republic.  Following the break-up of the Soviet Union, the company was privatized in 1992 as Česká zbrojovka a.s. PLC.  CZ currently employs more than 2000 people, making it one of the largest firearms manufacturers in the world.

Back in the early 1970s, military orders were starting to drop-off and the Ministry of Foreign Trade requested CZ to begin work on the design of a military and law enforcement pistol which might have export potential to Western countries.  The design brief was for a pistol chambered for the 9x19mm round, with a high-capacity magazine and capable of being carried “cocked and locked” (i.e. with the hammer cocked and a manual safety applied).  Chief designer František Koucký (with some help from his brother Josef) produced a design where the slide of the pistol ran inside rails on the frame, rather than the conventional approach where the slide is outside of the frame.  This was claimed to give smoother and more controlled slide movement, though it did mean that the slide serrations were a little small.  Czech architect and designer František Crhák was also asked to provide ideas on the visual design of the pistol, and the result was a simple, distinctive and instantly recognisable design.

Early model CZ 75

Functionally, the all steel CZ 75 is a relatively simple design using a modified Browning short recoil operated, locked breech action.  Early prototypes were single action only but the final version featured both double and single action with a half-cock position for the hammer in order to make manual de-cocking safer (because it can be carried cocked but with the safety engaged, the manual safety does not incorporate a de-cocking function).  Mass production began in 1977 and the CZ 75 quickly gained a reputation for power, accuracy and reliability.  It also has superb ergonomics, combining the slim pointability of a 1911 with the advantages of a double-stack magazine.

During the early 1980s, the CZ 75 became one of a small group of pistols referred to as the “Wonder Nines“.  Police in the US were still largely armed with revolvers at this time, and a number of influential gun writers including Jeff Cooper and Robert Shimek urged the adoption of 9mm handguns with large capacity magazines which could be carried ready to fire, but with a manual safety.  The CZ 75 was one of the pistols identified as a Wonder Nine and it was eventually adopted by some US Police Departments as well as by police users in the Czech Republic and Turkey.  The CZ 75 and its derivatives have also become very popular as target shooting and self-defence weapons around the world.

CZ 75B

The earliest versions of the CZ 75 featured a rounded trigger-guard and a spur hammer though these were quickly replaced on the CZ75B with a combat style trigger-guard and a rounded hammer.  Subsequent versions have included the select fire CZ 75 Automatic and the aluminium framed compact P-01.  More recent pistols from CZ such as the polymer framed P09 Duty continue to use the internal slide and other operational features from the original CZ 75.  The CZ 75 has also been used as the basis for several other handguns including the IWI Jericho 941 series, the Tanfoglio TZ-75, the Chinese Norinco NZ-75 and the Springfield P9.

The ASG CZ 75

Danish group Action Sport Games A/S (ASG) produce a range of CO2 powered 4.5mm semi-auto and revolver replicas.  ASG have a licensing agreement with CZ and a number of their replicas are based on CZ designs.  The ASG CZ 75 is an all-metal licensed replica of an early CZ 75 featuring blowback, a full-size drop-out magazine and full CZ markings.  Up to 17 steel BBs and the CO2 are stored in the magazine and all controls from the original are replicated visually and operationally.

Packaging and presentation 2.5/5

The ASG CZ 75 comes in a card box with a polystyrene insert shaped to fit the pistol and extras.  It is supplied with a hex tool for removal of the magazine base plug, a small box of steel BBs and a very short user manual.  The manual doesn’t mention the full and half-cock hammer positions or tell you how to field strip the replica.

Visual accuracy 9/10

Dimensionally, this is a very good replica indeed.    The lines of the original and the shape and location of sights, controls and grips are precisely the same.  Even the distinctive tiny, silver hammer pin retaining peg is in place.  The magazine on the ASG CZ 75 does have a larger base than the standard CZ 75 magazine.  However, CZ provide an extended magazine for the CZ 75 which increases capacity to 18 rounds, and the magazine on the ASG version is based on this, so it’s a reasonable solution to the need to fit a 12g CO2 cartridge inside the mag.

Later model CZ 75 SP-01 fitted with high-capacity magazine

The finish on the replica is a semi-matt black compared to a fairly glossy black finish on the original, but it looks reasonable and it’s close to the finish on later models of the CZ 75.  The trigger is chromed and outer barrel is finished in polished alloy on the replica, which looks good and replicates the finish on the original.  Markings are fair.  The “Model 75 Cal. 9 Para” on the left of the slide is correct though the “Made in Czechoslovakia” text which appeared on the left side of the frame of early versions of the original is missing and the CZ logos on the slide and grips are modern style rather than the 70s version.  There is also additional white ASG text on the right of the frame, but at least it’s small and fairly discreet.

Functional accuracy  14/15

The ASG CZ 75 features blowback operation and the slide moves through a full range of movement.  The slide lock/release works as it should and the slide locks back when the last round is fired.  Like the original, the hammer has a half-cock and full-cock position.  On the cartridge version this is used to safely de-cock a loaded pistol – the hammer is de-cocked only from full-cock to half-cock.  This is probably not something you’ll be doing often on a replica, but it’s nice to see such attention to functional detail.  With the hammer in the full-cock position, the pistol can be fired in single action.  With the hammer in the half-cock position, the pistol can only be fired in double action.  The manual safety can be applied only with the hammer in the full-cock or half-cock position.  With the hammer fully down, the pistol can be fired in double action, though on mine this is notably stiff (but it does seem to be improving with use).

Hammer at half-cock (top) and full-cock (bottom)

The ASG CZ 75 can be field stripped in the same way as the original (though this isn’t explained in the manual).  To remove the slide, the magazine must be removed and two marks on the left rear of the slide must be aligned.  The slide release can then be pushed out from the right and removed from the left, and the slide can then be moved forward off the frame.  It’s very similar to the takedown procedure on any 1911 style pistol.

Slide alignment marks (arrowed, left), slide stop removal (right)

Overall, this is a very good functional replica of the CZ 75.  It accurately replicates trigger action, slide movement and locking and takedown and it’s very close to weight of the original.  This would probably make a good training aid for anyone who also owns the cartridge version.

Shooting  35/40

To load the magazine with CO2, the plastic cover on the base must first be removed.  There is a small plastic button in the centre of the base which is pressed, then the plastic cover can be slid off to the front.  This exposes the tightening plug which can be removed using the supplied hex key (though it also has a large slot so a coin or screwdriver can also be used).  The plug must be completely removed so that the CO2 can be inserted from the bottom of the mag.  Once it’s in place, the plug is replaced and tightened until the cartridge pierces, which it generally does cleanly and without any major loss of gas.

Up to 17 steel BBs are then loaded into the magazine.  The follower doesn’t lock down, so it must be held in place whilst you are loading.

The magazine is then replaced and you’re good to go.  The slide must be racked to prepare for the first shot and, due to the design of the slide, the area of serrations is fairly small.  This, combined with a strong return spring, means that you do have to grasp the slide strongly to get a good grip.  Racking the slide also cocks the hammer, so most of your shooting will be done in single action.  Fortunately, the ASG CZ 75 has a very nice, light, true single action trigger.  There is some free-play, but the pull is short, light and consistent.  Blowback is strong and snappy and this replica shoots with a reasonably loud bang.  Sights are simple and basic (no white dots here), but clear and perfectly adequate.

The CZ 75 can be fired in double action if the hammer is fully down or in the half-cock position.  With the hammer at half-cock, the double action trigger is moderately heavy, though smooth and consistent.  With the hammer down, the first part of the double action pull is much heavier, though this does seem to be improving with use.

When I started shooting the CZ 75 accuracy was reasonable, with groupings on average of around 2″ at six yards, though this did seem to vary.  One magazine of BBs might group at 1½”, while the next might be 2½” or even 3″.  It felt adequately powerful and I have no reason to doubt the claimed 300+ fps.  In temperatures of around 26 – 28°C I was getting between 50 and 60 shots per CO2.  Power doesn’t seem to drop off, and accuracy and power are maintained until virtually the last shot.  The slide locks back reliably when the last shot is fired. Good, strong recoil effect and a loud report make this a satisfying replica to shoot.  It also inherits great ergonomics from the original, the single action trigger pull is wonderfully light and short and the sights give a clear picture.

Ten shots, six yards, semi-rested. Not bad…

The sights are non-adjustable and my CZ 75 generally shot around 1½” low and to the left at six yards.  Or at least it did until I adjusted the hop-up.  Hang on a minute, I hear you say, this is a 4.5mm replica, so it can’t have hop-up.  And I’d agree, except that it does.  There is no mention of adjustable hop-up in the manual but there is a screw on the outside of the inner barrel housing which adjusts how much the hop-up nub projects into the inner barrel, just the same as you find in many 6mm replicas. This is the first time that I have seen functioning hop-up in a 4.5mm replica.  Most people will tell you that there is no point in having hop-up on a replica firing steel BBs because these are too heavy for the backspin to substantially affect their flight.  But this doesn’t appear to be true…

Hop-up is adjusted by turning the slotted screw on the base of the hop-up housing on the inner barrel.  If you turn this too far, it affects operation of the gun – with the hop-up turned all the way up (i.e. the screw turned all the way clockwise) the loading nozzle is locked in the inner barrel and the slide won’t retract.  Easing it off a little allows the slide to retract, but leaves the blowback sluggish and the slide fails to lock back.  Easing it off further frees everything up and restores normal operation.

You can just about see the hop-up nub in this picture – it’s the flat area on the right (top) of the inner barrel.  This shows the nub adjusted for maximum effect.

But, how does it affect shooting?  On a 6mm replica, hop-up is mainly used to adjust vertical placement of shots.  At 6 yards, the effect is minimal, but at longer ranges it’s more noticeable.  However, I have spent a fair amount of time playing with the hop-up on my 6mm replicas, and I have also found that adjustment tends to affect groupings at six yards – there is often a “sweet-spot” which provides the best and most consistent groupings, and this can only be found by experimentation and test. I carefully cleaned the inner barrel and hop-up rubber on the CZ75 and made small adjustments to the hop-up.

And the results were much better.  The lateral spread on groupings was reduced and much more consistent.  By further adjustment of the hop-up I was able to get the CZ 75 to produce consistent groupings of under 2″ centred close to the point of aim.  Result!

Ten shots, six yards, rested, after cleaning the barrel and hop-up rubber and adjusting the hop-up. A notable improvement compared to shooting results before adjusting the hop-up.

Quality and reliability  13/15

I haven’t had any functional issues with my ASG CZ 75.  It loads and holds gas without leaks and everything works reliably.  When shooting the first few magazines, there was an occasional double loading of BBs which resulted in a notably less powerful shot.  However, this hasn’t recurred and I assume it’s just part of the process of wearing in.  Like most ASG replicas, this feels well made – the slide fits tightly and with almost no play, all the controls works crisply and positively and the grips seem robust and don’t flex or creak when the pistol is gripped.

The finish is good, but not perfect.  There a couple of areas on the frame and magazine where there are minor flaws in the paint.  You have to look very closely to see them, but they appear to be slightly thicker areas of paint which have dried to leave a slight discoloration.  Now, I have noticed that the finish on the previous ASG semi-auto replicas I have owned seemed to last better than the average.  On most modern replicas, the finish is applied electrostatically, which gives an even, but very, very thin coating of paint.  On some replicas this produces a finish so fragile that it wears if you look at them hard enough.  I don’t know whether these slight defects in the paint on the CZ 75 imply that ASG use some other process to apply a thicker and more hard-wearing finish?

A very minor issue is that there is a tiny area of wear to the finish on the very back of the long beavertail.  I’d guess that the equally long hammer is clipping the edge of this as the slide retracts under blowback.  There is also a little wear inside the slide where the outer barrel is rubbing against the inside of the slide.  It’s not major, and because the outer barrel is polished alloy, there is no finish to be worn off and this wear isn’t apparent unless you remove the slide and look inside.  Otherwise, the finish on my ASG CZ 75 is holding up very well indeed.

Overall Impression 14/15

I hadn’t realised how much I have got used to replicas of polymer framed pistols until I picked up the hefty, all metal CZ 75.  It’s notably heavier than, for example, the polymer framed ASG CZ P-09 Duty, and it feels good.  OK, if I had to carry a pistol round all day, I’d probably appreciate the light weight of more modern guns.  But as an occasional target shooter and replica collector, I really enjoy a weighty pistol.

Like most ASG replicas, it seems to be well made too.  The finish looks good and (if my past experience of ASG replicas is a guide) should be durable too.  I also appreciate the attention to detail in things like the half-cock position for the hammer, the light single-action trigger and the ability to field strip.  Like the original, it isn’t a complicated design and the sights and controls are simple and basic but easy to use.  Niggles?  Very few really – the slide serrations are rather small and it can be difficult to get a good grip on the slide, the double action trigger pull seems sticky in the first stage (though this seems to be improving with use) and I don’t especially care for the extended base to the magazine.  Otherwise, this is very good indeed.

Conclusion

The first thing I want to mention here is the inclusion of adjustable hop-up on the ASG CZ 75. And the fact that it works, despite the fact that most people will tell you that steel BBs are too heavy to be affected by hop-up. Can we have hop-up on more 4.5mm replicas please?  I had almost stopped buying steel BB shooting replicas because of the lack of hop-up adjustment.  Pistols like the Tanfoglio Witness and the Cybergun GSG92 and Sig Sauer P226 X5 are fantastic replicas.  But whether individual examples shoot above, below or on the point of aim seems to be purely a matter of luck and given that none have adjustable sights and you can’t try different weights of BB, there is nothing you can do about it other than fitting an optical sight.  Being able to adjust the vertical centre of groupings on a 4.5mm replica by using hop-up adjustment feels like a real step forward.

Other than this very welcome feature, the decision on whether you want one of these is pretty easy: Are you bored with 1911s, Beretta 92s and plastic framed pistols?  Do you want a replica of something a little different?  Then you need one of these.  For collectors, it’s a very nice replica of a transitional design which comes somewhere between the 1911, the Hi-Power and more modern pistols like the Sig P226 and the Glock 17.  For shooters it’s a powerful, weighty, reasonably accurate BB pistol with strong blowback, a true single-action trigger and great ergonomics.  It’s also fairly frugal with CO2, it’s relatively inexpensive, it looks good and it feels great in the hand compared to most polymer framed replicas.  Surprised?  You bet!  But in a good way…

Total score: 87.5/100
