Glock 22 Gen 3 by Gernel Domingo, Verified Owner, December 29, 2024
First time using DPM recoil spring. I haven’t gone to the range just yet. But I can definitely feel the difference with using dummy rounds and dry firing.

Product Info for DPM Mechanical Recol Gens 1-3 Reduction System

This DPM Mechanical Recoil Reduction 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. Also included with the system are 2 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.image
