 Recoil Spring Assembly Instructions

The DPM FN Herstal FNX-45 Tactical Recoil Reduction Spring Rod 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.

The DPM FN Herstal FNX-45 Tactical 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.

    I bought this product after I bought my FN .45 Tactical, the pistol is great but due to the stainless steel upper it has a tendency to rock when shooting. This product tamed that rocking action and now it shoots so sweet. I highly recommend this product if recoil is an issue for you.
