Marushin Auto Mag

There are big guns, there are stupidly big guns and then there’s the Auto Mag, for people who think the Desert Eagle is a compact pistol.

Ah, the 70s. The decade that taste forgot. Big hair, big cars, big movies and really, really big guns. In many ways the Auto Mag pistol typifies the excess of the 1970s. It was bigger and more powerful than just about any other semi-automatic handgun before or since. It was also almost completely pointless. It certainly produced the power of a .44 Magnum revolver with a little less recoil, but generally, the only time you’ll see a gun this big is when it’s fitted with wheels and being towed behind a team of horses.

Somehow, this seemed cool in the 1970s. And no, that isn’t me. My hair was way longer than that in the 70s.

The production history of the real steel Auto Mag was relatively brief and these exist now only as historical oddities and collector’s items. So, it’s perhaps surprising that in 2003 Japanese company Marushin introduced a gas powered, blowback replica of the Auto Mag. But I’m glad they did. Just like the original, production of this replica was brief and you can now find these only on the used market. But it’s worth seeking one out if you can – if you have any interest in handguns and replicas, I defy you to pick one of these up and not have a smile on your face.

Real Steel Background

The idea which became the Auto Mag pistol came from Harry Sanford, a US businessman, in the late 1960s. Sanford wanted to produce a semi-automatic pistol which was capable of shooting the powerful .44” Magnum round, but with less recoil and a larger ammunition capacity than the Smith & Wesson revolvers for which the round was originally designed. Because of the power of the round for which this pistol was designed, a conventional moving slide was rejected in favour of a cylindrical bolt with eight radial locking lugs (similar to the bolt used on the M16/AR15 rifle) and a cocking knob with grip serrations that projects from the back of the main body of the pistol. The final design was complex and required extensive manual input during manufacturing to ensure that the stainless steel elements operated correctly together.

The Auto Mag was offered in two versions. One was chambered for the mighty .44 AMP round which propelled a 15.5 gram projectile at up to 1,650fps (that’s around 2,000 Joules of muzzle energy folks!). The other was the .347 AMP version which used a necked-down version of the same casing to fire a .357” round at over 1,700fps. The only difference between the two versions was the barrel (which was interchangeable). Barrels were available in 6½” and 8½” and with or without vent ribs. Magazine capacity was 7 rounds and all versions featured adjustable sights.

But just who were the customers that the Auto Mag was intended to appeal to? Its sheer size and weight ruled it out as a military or police sidearm and (outside Hollywood) for the same reason it was never going to be a viable concealed carry weapon. You can shoot targets and tin cans just as effectively with much cheaper .22” rounds (a .22LR round is less than one tenth the cost of a .44AMP round) and those don’t generate wrist-snapping recoil and blinding muzzle flash. There are certainly people who hunt using large calibre pistols, but their numbers are relatively low and anyway, the Auto Mag doesn’t provide a massive advantage over a revolver as a hunting weapon. I suppose there will always be people who feel a pressing need to win any “my gun is bigger than your gun” argument, but again, the numbers involved are fairly small. In most ways, the Auto Mag was an answer to a question no-one was asking.

Don’t you love Hollywood? Only there would a police officer choose a 14” long pistol weighing four pounds as a concealed carry weapon. In Sudden Impact (1983), the fourth of five films featuring Clint Eastwood as “Dirty” Harry Callahan, the main character briefly swapped his iconic S&W revolver for a .44AMP  Auto Mag.

In mid 1971, production of the Auto Mag pistol started but the business model adopted was, well, let’s be charitable here and call it “quirky.” It has been estimated that each Auto Mag pistol cost around $1,200 to manufacture in 1971 (and remember that the purchase price of something like the reliable and well-regarded Colt Python revolver was just over $200 at that time). To overcome this problem, the company decided to sell each Auto Mag at a price of just $247.50. This meant that they would lose almost $1,000 on every Auto Mag sold, but the idea was that this would generate such massive demand for this pistol that subsequent volume production would reduce manufacturing costs and investors would queue up to pour money into the company. This was a brave (or possibly misguided) approach and in the event, very few people bought Auto Mags. It was therefore no great surprise when on May 3rd 1972, after producing less than 3,000 pistols, the Auto Mag Corporation of Pasdena declared bankruptcy.

However, that wasn’t quite the end of the Auto Mag story. After AMC went bust, several other companies were granted licenses to manufacture the Auto Mag. Some of the best known include TDE Corporation, OMC Corporation and High Standard Corporation. Altogether, around 9,500 Auto Mag pistols were produced between 1971 and 1982. These were sold at prices of up to $3,250, much more realistic in terms of manufacturing costs but hardly likely to encourage large numbers of sales.

This is one of the later Auto Mag pistols produced by AMT. It doesn’t look anything like the original version but, is it just me or does it look a whole lot like the pistol from the original Robocop movie?

The Auto Mag name was also revived by the Arcadia Machine and Tool Company of Covina, California who produced both copies of the original pistol and a series called the AMT AutoMag II, III, IV and V in the 1980s and 1990s. However these latter pistols were actually of a completely different design and had nothing to do with the original Auto Mag. There are still people who buy and collect Auto Mags in the US, but with ammunition becoming difficult to find (and costing anything up to $8 per round if you can find it!) these aren’t particularly popular shooters.

The Marushin Auto Mag       

This replica is manufactured by Japanese company Marushin and is a replica of the first version of the .44 AMP Auto Mag Model 280 manufactured by the Arcadia Machine and Tool Company of Covina, California. Most parts of this replica are made of high density plastic, though the hammer, trigger, bolt, magazine and some internal parts are metal. It’s a blowback replica where gas is stored in the full size drop-out magazine but it’s designed for 8mm BBs rather than the more common 6mm variety. The Marushin Auto Mag was available only with an 8½” barrel and in black finish with black grips or silver polished finish with brown wood effect or black grips. The one that I owned had a very glossy and rather attractive black finish though I have also seen examples with a more matt finish. As far as I am aware, this replica was introduced in 2003 but is no longer available new though used examples occasionally turn up for sale.

This was often (though not always) sold as the “44 Auto Mag CLINT1”. The “CLINT1” refers to the use of the Auto Mag by Clint Eastwood in the movie Sudden Impact. This movie was made in 1983 after production of the Auto Mag had ended. However, two pistols were built specially for use a props in the movie and these were given the serial numbers “CLINT1” and “CLINT2”. Despite this, the Marushin Auto Mag doesn’t feature a serial number.

I believe that Marushin also produced a very similar non-blowback version of this replica. However, I know nothing at all about the non-blowback Auto Mag other than that it is also now out of production.

Packaging and presentation (2.5/5)

The Marushin Auto Mag usually comes in a monster card box with a polystyrene insert though I have seen silver finish versions which were supplied in a light alloy case. This replica comes with a small bag of 8mm BBs, a couple of hex keys for adjusting the hop-up and a manual.

This is the box for the silver finish version which also came with a light alloy case.

Visual accuracy 9/10

As far as I can tell given that I have never actually seen a real steel Auto Mag, this Marushin replica is completely accurate in terms of size, placement and shape of controls and markings. The only visual difference is that on the right side of the upper receiver (in the position where the serial number is stamped on the original) this has the text “MFG.MARUSHIN.”

Markings are engraved deeply into the high-density ABS receiver and look much, much better than the more usual painted or laser etched markings.

Functional accuracy 14/15

Just like visual accuracy, the functional accuracy of this replica is 100%. All controls are present and operational as per the original. The bolt must be pulled back and released to cock the pistol for the first shot and the bolt locks back when the last shot is fired. Like the original, this is single action only. The takedown lever on the left side of the frame is operational and takedown allows the upper receiver and barrel to be removed leaving the bolt and bolt carrier mechanism in-situ.

Shooting 32/40

Preparing the Marushin Auto Mag for shooting is no different to any other blowback 6mm airsoft replica. Put up to 10, 8mm BBs in the magazine, fill the magazine with green gas through the valve in the base, insert the magazine then pull back the bolt and release and you’re ready to shoot.

The Marushin Auto Mag is fairly loud, certainly louder than most 6mm replicas, and the felt recoil from the moving bolt is strong. The 8mm BBs hit the target with notably more authority than 6mm BBs. The very long stretch from the front to the rear sight gives the Auto Mag an exceptional sight radius and the fact that the rear sight is fully adjustable means that you can get the point of aim and the point of impact to coincide precisely.

Oddly, given its size, I didn’t find the Marushin Auto Mag at all clumsy to shoot. The grip is reasonably sized and the balance is good and I found this less of a stretch than, for example, several Beretta 92 replicas I have owned. The reach to the single action only trigger is also reasonable and the trigger is very light and with a precise and consistent break. I found accuracy to be reasonable, with groupings of 1” – 1½” at 6m. I ran six shots from my Marushin Auto Mag over a chronograph on a fairly chilly day in Scotland and I got a low of 240fps and a high of 260fps. Let’s call it an average of 250fps, though I have seen claims of anything up to 400 fps for this replica. I generally got about two full magazines plus a few extra shots for each fill of green gas.

4.5mm steel BB (left), 6mm alloy BB (middle), 8mm plastic BB (right)

This is the only 8mm replica I have owned, and I have to say I enjoyed shooting these larger BBs a lot. They may be only 2mm larger than the more usual 6mm BBs, but they feel notably bigger, they’re less fiddly to pick up and load and they smack into the target a lot harder than smaller BBs. I have a feeling that they’d also probably be better at longer range than 6mm BBs as well, though I never did get the opportunity to try this out. The Marushin Auto Mag does have adjustable hop-up though I never tried adjusting it – mine shot just fine as it was and the adjustable rear sight has a good range of adjustment.

Generally, I enjoy shooting smaller replicas. I have no idea why – I don’t have especially small hands, but for some reason I find the grip on things like Desert Eagle and Beretta 92 to be just too big to get a comfortable hold. However, I didn’t have any problem with this replica. And this is so ridiculously big that it’s just fun to shoot. Look at the picture below of my Auto Mag next to one of my Umarex Walther CP88s. The CP88 isn’t particularly small, but next to the Auto Mag it looks like a pocket pistol! But look at the grips – if anything, the Auto Mag has a smaller grip and a shorter reach to the trigger which is why it’s comfortable to hold and shoot.


Quality and reliability 12/15

I’m afraid that the mainly plastic Marushin Auto Mag does feel rather light when you pick it up. Its sheer size makes you expect something very heavy indeed, but although it weighs over 2 pounds, it doesn’t weigh as much as it looks as if it should. In some ways that’s good – I imagine shooting the four pound real steel version would get tiring very quickly, but that isn’t a problem here. But I can’t help that wish that more metal had been used in the construction of this replica. The most striking thing about the Auto Mag is its size, and if this replica had the weight to match, it would really stand out in any collection.

I did have a few minor issues while shooting my Marushin Auto Mag. The bolt would occasionally fail to lock back on empty and sometimes a BB would not feed into the magazine, leaving me shooting just green gas. However, in general this was fairly reliable considering that I bought it as a well-used example and the fact that most of the external parts are made of plastic means that you won’t have to worry about the finish chipping off (on the black version at least, I don’t know how the silver version is finished). However, on some of the painted metal parts including the bolt and trigger, there was some paint wear on mine.

Overall impression 11/15

The Auto Mag pistol is bigger than a very big thing and that bigness is first and main thing that strikes you about this Marushin replica. The second thing that strikes you when you pick it up is that it feels rather light and a little toy-like (especially with the metal magazine removed). That’s a pity because Marushin also make an all-metal, shell ejecting PFC version of the Auto Mag and there seems no reason (other than cost) that they couldn’t have used more metal here.

However, if you ignore the lack of weight, this is a sturdy, well-made replica which shoots reasonably well. I also found that, despite its size, it was easy to find a comfortable grip, something I haven’t found with all large replicas.

Conclusion

This is a good replica of a relatively little known pistol. I particularly enjoyed shooting with 8mm BBs instead of the more usual 6mm versions and I’d like to see more replicas in this calibre. These larger BBs probably make this replica too powerful for skirmishing, but they are ideal for the kind of target shooting that I do.

This is the more common matt black finish

Do you really need a replica this big? Of course not! On the original, the size is justified because the Auto Mag shoots a massively powerful round capable stopping a charging T-rex. However, this replica isn’t any more powerful than most and is less powerful than some. But that doesn’t mean it isn’t fun. If you do want one, your biggest problem will be finding a used example as these aren’t made any more. The polished silver version with wood effect grips and which came with an alloy case looks particularly good, if you can find one. So, go ahead, make your day – get yourself one of these.

Total score 80.5/100

Cons

Mainly plastic and fairly light

Not especially powerful

Hard to find nowadays
