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.Non-captive design allows the use of different recoil springs to tune the action of the pistol.
Made from solid steel and hardened to 55 on the Rockwell "C" scale.
Gives better support and alignment than the factory Glock rod.
These rods permit the user to keep the factory recoil assembly intact without having to disassemble it to use the factory guide rod with other springs.
The Wolff guide rod is for use with a Wolff recoil spring - it will not work with a factory Glock spring.
Remove the entire factory recoil assembly and replace with this Wolff guide rod and a Wolff recoil spring (must be purchased separately).
