Replacement recoil spring. Some fitting may be required.See product description
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
recoil and battering the frame. Too heavy a spring and the slide is hard to open and may not cycle completely, jamming the
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 pistol.
