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 29, 30 and 36 in 10mm Auto and 45 ACP respectively.
It contains a Wolff CNC heat treated hardened steel guide rod and one 17 pound recoil spring
Use with Wolff recoil springs (142633) designed for the Wolff guide rod
Black Oxide finish
Factory new production Glock recoil springs are 16 pounds.
Recoil springs fit over a pistol's guide rod and control how the pistol's slide functions.
In general, heavy loads need heavy springs and lighter loads need lighter springs. There is no hard and fast rule as to how
much "Spring" a pistol needs. Too light a spring and the pistol opens and closes early and hard, increasing the felt reoil and
battering the frame. Too heavy a spring and the slide is hard to open and may not cycle completely, jamming the pistol.
Shooters who are using +P ammunition or self defense ammunition will likely need heavier recoil springs.
Shooters who are using target ammunition may be able to use lighter recoil springs.
Installation requires disassembly and reassembly of the slide from the pistol.
