MECHANICAL RECOIL REDUCTION SYSTEM
This system works due to the multi spring intricate rod (three 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 two different spring plugs and three different external springs. 
The spring plug with the marked groove is offering a heavier buffer feeling and the spring plug with flat surface offers a lighter buffer feeling (slide full open position). The external springs are different in length so the shooter can fine tune the pistol on the opening and locking positions (slide on the battery) according his/her personal standards.
