The SI Frame Shock Buffer is a polyester based thermoplastic polyurethane barrier that is uniquely designed to absorb recoil. The FSB was designed to increase durability between the areas of the metal slide and polymer frame while also decrease the amount of overall wear. The relief gained will also decrease the shock to your hands which prevents muscle fatigue and allows for more control for the next shot. Youll get a smoother and cleaner shot with a simple yet effective upgrade in the Strike Industries Frame Shock Buffers.
