Add weight to reduce muzzle flip and decrease follow up shot time of your SR9/SR40 with our Assembled Stainless Steel Guide Rod. Also allows use of different spring rates to tune the pistol to your needs and handloads. Adds a little bling for those folks looking for that to. 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.
