M&P guide rods in steel and tungsten for improved recoil control and consistent cycling in competition. Full-length guide rods add mass to slow return speed and reduce muzzle flip — noticeable improvement for Production and Carry Optics shooters running factory or reduced-power recoil springs. Compatible with M&P 9 2.0, M&P Pro, and Performance Center variants. Pairs with aftermarket spring kits for a fully tuned recoil system. Fast same-day shipping on most orders at Shooters Connection.
