Description DPM Mechanical Recoil Reduction System for Sig Sauer P320 XCompact  3.6″ Barrel 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 millimeters 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 DPM Mechanical Recoil Reduction System is a direct replacement for the stock recoil rod and does not change the configuration of the pistol. As always, DPM products are designed and developed with user’s safety as a priority. Exceptional manufacturing and engineering using high-end materials. *B.O.S.S: Black Oxide Stainless Steel  its an innovative coating technology applied usualy on the visible parts of the recoil system. The spring plug should Always be Installed when the DPM Recoil Rod and springs are used.   Recoil System Forces: Slide in battery (idle position) Short: 3.6kgs/7.9Lbs Medium: 3.9kgs/8.5Lbs Long: 4.2kgs/9.25Lbs Slide full open position (approx.): Short: 7kgs/15.4Lbs Medium: 8kgs/17.6Lbs Long: 9kgs/19.8Lbs Overall Advantages Faster follow up shots Improved firing speed Slide and Frame Protection Elimination of jams Significant recoil reduction Better double-tap concentration Better control and greater accuracy SIG P320 X-Compact Instructions
