The popular firearms accessory makers at Strike Industries recently debuted their new G4 Slidecomp Glock compensator. It’s currently on pre-order at their site for $79.95. It only fits 9mm Gen 4 Glocks (not Gen 3 or earlier Glocks) and no threaded barrel is required and no permanent mods are done to your gun. It also works with open-bottomed holsters. We ordered one so look out for our review after they ship.
