DPM Recoil Reduction System for Walther PDP F Series 3.5″

About the Walther PDP F Series 3.5″ by DPM Systems:

The Walther PDP F Series 3.5″ 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.

This Mechanical Recoil Reduction System is a direct replacement for the stock recoil rod and does not change the configuration of the pistol. As always, DPM products are designed and developed with user’s safety as a priority. Exceptional manufacturing and engineering using high-end materials.

Will Fit: Walther Walther PDP F Series 3.5″

Walther PDP F Series 3.5″

The Walther PDP F-SERIES 3.5″ 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.

The spring plug must always be installed when the DPM Recoil Rod and springs are used.

DPM Telescopic Recoil Reduction System for Walther PDP F Series 3.5″

The Telescopic Recoil System is a direct replacement for the stock recoil rod and does not change the configuration of the pistol. This system works due to the multi spring intricate rod (3 springs) and controls the functionality of the pistol, using more efficient the small internal space of the subcompact pistols.

The 3 springs of the system are aligned and gradually compressed, so as to offer an elastic effect of the slide travel and to control the movement of the slide, so it never rams on the frame. The system includes 4 external springs (2 x 1.15mm wire diameter and 2 x 1.2mm wire diameter), all with different power rates, with the longer spring always being the stronger, so the shooter can fine tune the pistol recoil with different type of ammunition according to his/hers personal standards.
