The TUNDRA suppressor is a super lightweight solution to pistol suppression. While it would be perfectly at home on a full size pistol, we highly recommend this little guy for your smaller (Glock 19, Sig 229, etc.) sized pistols. The overall size and weight of this can make it an absolute pleasure to shoot on any 9mm and the included "fixed barrel adapter" means it is ready to rock on your 9mm carbines as well (assuming they are threaded to 1/2x28). Performance from this suppressor is what you would expect out of a name like GEMTECH. They have yet to let us down and this pistol can is no exception. These will be the last of our stock so get them while the getting is good! This suppressor comes with the 1/2x28 piston as well as a fixed barrel spacer for free!
