DPM Mechanical Recoil Reduction System for FN Herstal FNX .45ACP 4.5″ & Tactical 5.3″ Barrel

The Mechanical Recoil Reduction System is a direct replacement for the stock recoil rod and does not change the configuration of the pistol. 

  • For changes to features, like comp set-up, threaded barrels, slide conversions etc., contact us via email at [email protected] before placing your order. In some cases, we need to determine whether a custom product is required. 

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.

The kit includes 2 external separate springs. The springs are different in length with the longest being heaviest when the slide is on the battery, so the shooter can fine-tune the weapon for his/hers personal standards.

Power Rates

Slide on the battery

  • Short Spring: 9lbs
