Add weight to reduce muzzle flip and decrease follow up shot time of your SR9, SR40, and SR9E series with our Assembled Stainless Steel Guide Rod. Also allows use of different spring rates to tune the pistol to your needs and handloads. The flat wound springs are made for us by ISMI, a leader in the spring market here in the U.S.A, to our specifications. Made on the same machines that make springs for Formula 1 and IndyCar race cars, made exclusively with aerospace specification alloys, these springs are made to last and provide a more enjoyable shooting experience. These are polished and assembled with Loctite to your needs. Pick spring rate and retainer screw color (polished stainless or blacked tool steel) and we'll assemble it as requested.
