Description

DPM MECHANICAL RECOIL REDUCTION SYSTEM

This 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.
