Strike Industries G3 Mass Driver Compensator Black Steel 9mm - Glock 19 Gen 3

The Strike Industries G3 Mass Driver Compensator is a purpose-built 9mm compensator engineered for the Glock 19 Gen 3 pistol. Machined from steel with a durable black finish, the Mass Driver represents a meaningful leap in compensator design - delivering aggressive muzzle-rise control in a clean package built around one of the most popular compact striker-fired pistols on the market.

The design centers on a widened bore that reduces baffle strikes and prevents keyholing, paired with a 2.5mm relief cut at the top rear of the device to vent unburned gases and keep the slide cycling smoothly. The compensator ships with a complete spring set - recoil spring, guide rod, and guide rod fitment washer - for straightforward installation on the Gen 3 Glock 19.

Measuring roughly 6.9" in overall assembly length, the G3 Mass Driver installs in place of the factory recoil assembly. This is the G3-variant (MPN G3MDCOMPC) configured for 9mm use and ships with all required comp hardware pictured. It is a strong choice for range, duty, or competition use, bringing proven recoil management to the Glock 19 Gen 3.
