Product Overview
DPM Mechanical Recoil Reduction System | Smith & Wesson M&P 4.6" (10mm & .45 Auto)
Overview: The DPM Mechanical Recoil Reduction System is a direct-fit replacement for the factory guide rod on Smith & Wesson M&P 4.6" pistols chambered in 10mm or .45 Auto. This multi-spring captured rod uses an internal three-spring architecture to control slide motion, dramatically reducing slide impact on the frame while allowing fine tuning with multiple external springs.

- Slide & frame protection: Internal buffering prevents the slide from ramming the frame.
