Guide rods are made of solid steel, hardened to a minimum of RC-55 and black oxide finished. They provide optimum performance for recoil springs through better support and spring alignment. Guide rods not listed with a recoil spring will require a Wolff recoil spring (available separately). These rods will not work with factory Glock recoil springs.
