Besides being the most authentic WWII collector's piece with true to original replicated frame, the Matrix M3 is also the most advantageous on battle! Unlike the ARES or ICS version, this M3 is equipped with a hi-capacity magazine (while taking the ARES Mid-cap) to give you the most fire-power in a versatile system!
The M3 was an American .45-caliber submachine gun adopted for U.S. Army service in 1942. The M3 was commonly referred to as the "Grease Gun" or simply "The Greaser", owing to its visual similarity to the mechanic's tool.
The Snow Wolf M3A1 is a perfect replica of the original which makes it great as a collector's item. The internal system is a high quality, innovative metal gearbox which makes it more than capable in the field.
Comparable to the ARES M3, which retails for $320, this redesign has a compatible gearbox but with better performance. The battery in this version is wired through the pistol grip with a cap, making it part of the gun, instead of in the magazine. The freed-up magazine is now a 520 round Hi-Cap, but the Snow Wolf can still take the ARES mid-cap.

"This is a pretty cool gun. It feels real and definitely has they build quality of the real one externally. It is actually more green than black like the picture shows, which is actually more accurate. I'm a high cap magazine fan personally so that's a plus. The retractable/removable stock is also a cool and accurate feature. Unfortunately it is fully automatic only, but so it the real one. The entrance for the battery compartment is a little cramped, you most likely won't be able to fit a regular NIMH in the hole. I had to buy a thin 7.4v lipo to fit it in the gun. Also the battery cover feels like it could get knocked off and lost pretty easily.

Incredibly realistic
Solid build
Good weight
Good rate of fire

Proprietary gearbox
Trigger feels a little loose
Possible problems finding replacement parts
Battery hole too small for NIMH
Battery compartment cover is easy to knock off and loose

So so:
Fully automatic only (but accurate for real weapon)
High cap mag (I like them, but some people hate them)

Overall I would recommend this gun if you are looking for a cool and realistic collectors item, that would also work on the field if you wish to play with it. THIS IS NOT A GOOD PRIMARY WEAPON, AND NOT A GOOD FIRST AIRSOFT GUN. It's worth five stars to me considering the personal circumstances of why I purchased it.

"This is a great little gun! I bought this in early September of 2017 and have taken it to several matches since. The weight of the gun feels close to the real steel (Which I've held and shot before, so I'm not just throwing crap out there) and the function is great too! Although you don't need to rack the bolt for the first shot like the real thing, I do appreciate that the "safety" is accurate: Closing the dust cover. (To fire, you open it. Pretty simple.)

It obviously has a much higher rate of fire than the real thing, but that's understandable. I went ahead and got a 7.4 LiPo with 1000mAh for mine, and the thing can run all day with it, outlasting all the M4s on the field.

The range isn't phenomenal, but it's a lot better than you would expect out of a small gun. Using .25s, I can easily walk it onto my victi- er, "targets" from about 50 yards. Granted, it looses some "oomph" by the time it gets there, so your rival might not feel it or just not call it. So do what I do and just mercilessly dump bbs into them until they call it out.

- Small and versatile, great for CTF and run-n-gun
- Accurate with .25s out to about 50 yards
- Decent range for an SMG
- Batteries are long lasting
- One full Hi-Cap mag can last a whole game and then some
- Very unique gun (I get loads of looks and comments/compliments on mine)

- FPS a little week (with .25s mine chronos at about 285fps)
- The battery door on the bottom of the handle comes off too easily (I lost mine already)
- .20s will swoop STRAIGHT UP after about 25-30 yards, no matter the hop-up setting
- Full-auto ONLY (Which is realistic, but requires trigger discipline if the game calls for semi)

NOTE: This gun has iron sights that are hard to use. This gun was never meant to be for range or accuracy, so I don't view this as a "con", I view it as realistic. They are functional and you can use them, but it's way simpler and faster to just walk in your shots. It's always on full-auto, the bbs are white, so it's really not that hard...

"I have had this S&T M3A1 for a little over a month and shot about a magazine a day (its a wind up and they claim it holds roughly 520bbs). It is mostly made of steel and even has that nice grayish parkerization color to it making it an accurate replica of the real steel. It fires at a slower cycle rate (compared to your standard M4, AK47, Thompson, etc.) the lower rpm on the airsoft smg is again perfect for closely replicating the real steel. It fire at a constant and accurate (I emphasize accurate) range maximizing at around 30 to 40 yards. I am a radioman for a WWII and Vietnam War airsoft teams and believe if you are in the market for a gun that could take a beating from the field, want a compact and reliable piece to carry into battle, then this is a great choice! A small con I have about the gun is that the magazine release button on my is a bit short and I have to hold the magazine while firing. I can solve the problem easily by filing a bit of the magazine catch and allowing the main part of the catch to grasp the magazine completely.
