DPM Mechanical Recoil System.
This system works due to the multi-spring intricate rod (3 springs) and controls the functionality of the gun. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame.
Also included with the system are 3 external springs and a Spring Plug so the user can fine-tune the weapon for his/her personal standards. The longer spring (more coils) is stronger and has a heavier pound rating than the shorter spring.
The spring plug must Always be Installed when the DPM Recoil Rod and springs are used.
Feel free to try any possible combination of the external springs to fine tune the pistol functionality, depending the power of the ammunition is used.
