GLOCK 40 GEN 4 10mm



DPM MRS for Glock 40 Gen 4 10mm 6″ Barrel

This DPM Mechanical Recoil System functions due to the multi spring intricate rod (3 springs). The third spring, which is contained within the rod, controls the movement of the slide so it never rams on the frame. The system includes 3 different in length washers and 2 external springs.

Washers differentiate only the buffer force (slide full open position) and the external springs differentiate only the slide closed position (slide on the battery). The shorter washer offers a light buffer effect and the longest washer offers the heaviest buffer effect. The external springs are different in length with the longer offering heavier slide travel and locking than the shorter spring.

Overall Advantages:

  • Faster follow up shots
  • Improved firing speed
  • Slide and frame protection
  • Elimination of jams
  • Significant recoil reduction
  • Better double-tap concentration
  • Better control and greater accuracy
