DPM Recoil Reduction System for Walther Q4 Steel & Polymer Frame (TAC/M2, OR) 4″ Inch. Barrel – Open Version

About the Walther Q4 Steel & Polymer Frame (TAC/M2, OR) 4″ Inch. Barrel – Open Version by DPM Systems:

The Walther Q4 Steel & Polymer Frame (TAC/M2, OR) 4″ Inch. Barrel – Open Version 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.

Will Fit: Walther Q4 models

Walther Q4 Steel & Polymer Frame (TAC/M2, OR) 4″ Inch. Barrel – Open Version

The Walther Q4 Steel & Polymer Frame (TAC/M2, OR) 4″ Inch. Barrel – Open Version 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 Mechanical Recoil Reduction System Walther Q4 Steel & Polymer Frame (TAC/M2, OR) 4″ Barrel Open Version

This DPM System works with six different buffer recoil springs which each one offers different spring force (Forces are listed at the end of the description).

The System is included with 3 external springs, 6 recoil springs and a safety pin.

The longer spring (more coils) is stronger and has a heavier pound rating than the shorter spring.

Feel free to try any possible combination of the external and buffer springs to fine tune the pistol function depending the power of the ammunition is used and according to your personal standards.
