DPM Mechanical Recoil Reduction System Walther Q4 Steel & Polymer Frames (TAC/M2, OR) 4″ Barrel Open
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.
