DPM MS For Smith & Wesson M&P 4.6″ 10mm

About the Smith & Wesson M&P 4.6″ 10mm DPM Systems:

The Smith & Wesson M&P 4.6″ 10mm 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.

Smith & Wesson M&P 4.6″ 10mm

The Smith & Wesson M&P 4.6″ 10mm 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.

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

This system works due to the multi spring intricate rod (3 springs) and controls the functionality of the gun. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame. Included with the system are 4 separate springs so the user can fine-tune the weapon for his/hers personal standards.The longer spring (more coils) is stronger and has a heavier pound rating than the shorter spring.
