DPM Mechanical Recoil Reduction System for Glock 20-21-21SF Gens 1-3

The DPM Mechanical Recoil Kit is a direct replacement for the stock recoil rod and does not require any modification to the pistol. 

National Tactical Officers Association Tested & Recommended.

The system works due to the multi-spring intricate rod (3 springs) and controls the functionality of the gun. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame.

Also included with the system are 2 separate springs so the user can fine-tune the weapon for his/hers personal standards.The long spring (more coils) is stronger and has a heavier pound rating than the shorter spring.

Power Rates
