The DPM Systems Captured Mechanical Recoil Reduction System works due to the multi spring intricate rod (three springs) and in some cases the system offers almost double force in the slide at the end of full open position, compared with the factory OEM spring and function like a buffer on the slide.From the above effect the slide stops smoothly on the frame and offer's less recoil.Further the moving parts of the pistol are protected, offering longer life to the pistol.
