MS-SPR/2 - SPRINGFIELD XD SERVICE MODEL 4" Inch BARREL .45 ACP
MECHANICAL RECOIL REDUCTION SYSTEM
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 1 spring plug and 2 different external springs. The spring plug must always be installed when the DPM Recoil Rod and springs are used.
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 positions (slide on the battery) according to his/hers personal standards.
