DPM Mechanical Recoil Reduction System for Beretta PX4 Storm Full Size 9mm and 40 S&W

Enhance the performance and shooting comfort of your Beretta PX4 Storm Full Size with the DPM Mechanical Recoil Reduction System. This precision engineered guide rod assembly is a direct drop in replacement for the factory recoil spring and installs without modifying your pistol. The multi spring design delivers improved slide control, reduced recoil, and smoother operation during each shot.

Advanced Multi Spring Technology

The DPM system uses a sophisticated three spring assembly that provides greater resistance at the end of the slide's rearward travel. In many cases, this design applies nearly double the force of the factory spring during full open slide position. This creates a buffering effect that protects the frame and reduces harsh impact during recoil.

The internal spring housed within the rod further regulates slide movement to ensure the slide does not slam into the frame. Combined, these features offer a more controlled shooting experience and help extend the lifespan of the pistol's moving parts.
