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.
