Strike Industries G3 Mass Driver Compensator 9mm Black Steel - Glock 17 Gen 3

The Strike Industries G3 Mass Driver Compensator is a 9mm Luger muzzle device purpose-built for the standard Glock 17 Gen 3 pistol. Machined from steel with a black finish, this compensator redirects propellant gas to noticeably reduce muzzle rise and felt recoil for faster, more controlled follow-up shots at the range or in defensive use.

The Mass Driver Compensator system features a widened bore to reduce baffle strikes and prevent keyholing rounds, paired with a 2.5mm relief cut at the top of the rear that aids in reliable slide cycling. Together, these design elements make the G3 Mass Driver a meaningful upgrade for shooters who want flatter, more predictable performance from their Glock 17.

This kit ships with everything needed for installation, including the comp main body, a matched recoil spring, guide rod, guide rod fitment washer, and guide rod head. Swap out the factory components and the pistol is ready to run.
