The above DPM Recoil Reduction System works due to the multi spring intricate rod (three springs) effect like a brake on the slide, but only before stopped on the frame to the last 6 to 8 millimetres of the movement.
In some cases the DPM Recoil System offer almost double force in the slide full open position compared with the factory OEM spring , so the slide of the pistol touching the frame gently and offering less recoil to the pistol.
Further the moving parts of the pistol are protected, offering longer life to the pistol.
Included with the system are 3 separate springs and 1 Spring Plug. These external springs are different in length (also in power) so the shooter can fine tune the pistol on the opening and locking positions (slide on the battery) according his/her personal standards. The longer spring (more coils) is stronger and has a heavier pound rating than the shorter springs.
The spring plug should Always be Installed when the DPM Recoil Rod and springs are used.
