DPM MRS for Glock 20-21-41-41sf  Gen 4 Captured Version

This DPM Mechanical  Recoil System functions due to the multi spring intricate rod (3 springs). This system offers almost double force at the end of full open position of the slide, compared to the factory OEM spring, and provides additional force that stops the violent rams on the frame.

From the above effect, the slide stops smoothly on the frame and offers less recoil.

Further, the moving parts of the pistol are protected, offering longer life to the pistol.

Finally, the design of the DPM Captured Version makes it easy to install on the frame.
