Sig Sauer P320 Full-Size Recoil Spring Assembly Instructions

The Sig Sauer P320 X Full Size 4.7″ Barrel Recoil Reduction Spring Rod by DPM Systems replaces the original factory guide rod/spring system and produces an advanced recoil reduction by absorbing the shock gradually and slowing the slide down before its impact with the frame of the pistol. Because the system is an interior modification of your pistol it will not change the external dimensions of the handgun, therefore there is no for a new holster, sights or any other accessory you own.

*B.O.S.S: Black Oxide Stainless Steel is an innovative coating technology applied usualy on the visible parts of the recoil system

The DPM  Sig Sauer P320 X Full Size 4.7″ Barrel recoil spring system works due to its multi spring rod design (three springs) by producing an advanced recoil reduction technique by gradually slowing the slide down before impacting the frame of the pistol using Spring No. 1 (see fig. below) and Spring No. 2. The third spring (Spring No. 3) which is contained within the rod itself controls the movement of the slide so it never rams on the frame.

DPM Mechanical Recoil Reduction System for Sig Sauer P320 X Full Size 4.7″ Barrel

This DPM System offers 9 Adjustable user settings.

The mechanism 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.

Also included with the system are 3 Spring Plugs and 3 External Springs   so the user can fine-tune the weapon for his/hers personal standards. The long spring (more coils) is stronger and has a heavier pound rating than the shorter spring. The Spring Plugs because of the different length change the total force of the recoil system (slide full open position).

The spring plug must always be installed when the DPM Recoil Rod and springs are used.
