Description DPM Mechanical Recoil Reduction System for SIG P320 Compact Carry – P320 M18 & AXG – WCP320 Wilson Combat  This system works due to the multi spring intricate rod (3 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 spring plug and 3 different external springs. The spring plug must always be installed when the DPM Recoil Rod and springs are used. The external springs are different in length, the long spring is heavy and the short is light so the user can fine tune the pistol on the opening and locking positions (slide on the battery) according his/hers personal standards.  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.
