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.
This kit is for the Glock 26, 27, and 33 in 9mm Luger, 40 S&W, and 357 Sig respectively.
It contains a Wolff steel 2-piece guide rod, 16 pound recoil springs, and a replacement firing pin spring.
Wolff guide rod and recoil spring combinations are non-captive.
