Strike Industries Mass Driver Comp for Glock 19 Gen3

Strike Industries Mass Driver Comp for Glock 19 Gen3

The Strike Industries Mass Driver Comp (MDC) is a compensator for Glock pistols that does not require a threaded barrel: it mounts onto the recoil spring assembly and utilizes exiting gases to counteract recoil. This version is designed for the compact slide of the third-generation Glock 19.

The operating principle is counter-mass: as the slide moves rearward, the compensator body moves forward, reducing muzzle flip. The enlarged aperture limits the risk of projectile contact, the 2.5 mm relief reduces wear on the slide face, and the profile remains flush with the original slide, allowing it to work with most open-ended holsters. Installation is reversible and does not modify the firearm; it is also compatible with numerous aftermarket threaded barrels.
