SIG SAUER P 239
The Sig Sauer P239 Mechanical Recoil Reduction System is a direct replacement for the stock recoil rod and does not change the configuration of the gun. 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. Also accompanying this system are two separate springs so the owner can fine-tune their firearms to match their personal needs and make them safer to use. This system is as well an inertia recoil reducer and makes the pistol easy to use.
