Last month I conned the nice guys over at Silencer Shop to lend me three different 9mm suppressors at the same time. I’ve been Jonesing for one to buy and the opportunity to test three side by side was too good to pass up. Earlier, we took a look at the AAC Illusion 9mm. This time, let’s take a closer look at the Gemtech GM-9 silencer.
As the name implies, it’s a dedicated 9mm can but it’s perfectly happy taming smaller calibers too. It’s rated to handle 9mm in full auto operation and also 300 Blackout subsonic rounds. Since the GM-9 is completely user serviceable, I wouldn’t hesitate to shoot .22LR through it either. Even though .22LR is filthy dirty and leaves carbon and lead deposits everywhere, there’s no harm done as long as you clean the silencer guts every few hundred rounds. For jacketed 9mm ammo, you don’t need to be nearly so persnickety with the cleaning regimen.
The GM-9 is an evolution from the earlier Tundra and Multimount models so the mounts remain compatible with Multimount adapters. With the available Multimount gear, you can use the standard L.I.D. Inertial Decoupler (booster) for normal pistol operation, a fixed thread mount for barrel guns, the three-lug mounting system for SMGs, Uzi, and CZ Scorpion mounts. The unit ships with the booster and a 1/2×28 TPI piston, which is standard for most pistols.
The GM-9, like many Gemtech models, is made to be light. As the unit is made primarily of 7075 T6 aluminum, weight is about 25% less than the AAC Illusion and maybe 15% lighter than the Surefire Ryder 9 that we’re going to check out next week. Depending on the mount, weight will be about 8.5 ounces.
