The Full Rundown
Less kick and faster follow-ups from your Glock 20/21 Gen 4.
The DPM system replaces the factory recoil rod and spring in your Glock 20, 21, 40, 41 Gen 4. A multi-spring rod controls the slide through its whole travel, so it doesn't slam the frame, the muzzle stays flatter and your next shot is on target sooner.
