DPM Mechanical Recoil Reduction System for Smith & Wesson M&P Shield M2.0 4″ Performance Center 9mm – 40S&W – 45acp
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. Included with the system are 3 separate springs so the user can fine-tune the weapon for his/hers personal standards.The longer spring (more coils) is stronger and has a heavier pound rating than the shorter spring.
