1911-2011 5″ Bull Barrel Edward Rivera

The DPM for 1911-2011 5″ Bull Barrel Edward Rivera BLACK OXIDE 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.

DPM Mechanical Recoil Reduction System for 1911-2011 5″ Bull Barrel BLACK OXIDE VERSION

This system works due to the multi spring intricate rod (3 springs) and controls the functionality of the pistol. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame.

The system includes 3 different in length spacers, a spring plug, a red pressure plate tool, a metallic cup screw tool and 3 different external springs. The long spacer offers a heavy buffer effect, moving to shorter spacers a lighter buffer effect is being noticed.

Washers differentiate only the buffer force (slide full open position) and the external springs differentiate only the slide closed position (slide on the battery).

Detailed instructions for installation also included. The external springs are different in length, the long spring is heavy and the short is light so the shooter can fine tune the pistol on the Opening and locking position (slide on the battery) according his/hers personal standards.
