The Strike Industries Mass Driver Compensator for Glock 19/G3 in 9mm (Strike Industries part no. SI-G3-MDCOMP-C) takes a different approach to pistol compensators: instead of adding reciprocating mass to the slide like a traditional barrel-mounted design, it’s driven by the hot gas expelled after the round fires and acts as a counterbalance system, separating from the operating components after ignition to keep cyclic speeds close to stock. A widened bore cuts down on baffle strikes and keyholed rounds, while a 2.5mm relief cut at the rear protects the slide face from lipping damage. It’s compatible with most aftermarket Glock threaded barrels on the market today.
