This DPM Mechanical system works due to the multi-spring intricate rod (three springs) and controls the functionality of the pistol. 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 1 Bushing, 1 Spacer and 4 different in length and tension external springs.

The external springs are different in length and tension, the long spring is heavy and the short is lighter so the shooter can fine tune the pistol on the opening and locking positions (slide on the battery) according to his/hers personal standards.

The active springs are offering additional buffer to the mechanism, this is a new innovation of DPM Systems. The 2 black coated springs have wire diameter 1.1mm and are stronger than the 2 silver and gold coated springs with wire diameter 1mm. The spacer is an optional use and provides +2.5 lb (approx.) to the total force of the system for each spring.
