Replacement recoil spring. Some fitting may be required.1911 style pistols with 5" slides
Factory 1911 recoil springs are 16 pounds in 45 ACP, 14 pounds in 38 Super, 9mm Luger, 38 Special Midrange, Colt Ace
22 conversion kit, and 19 pounds in 40 S&W.
The Delta Elite 10mm uses a dual factory spring rated at 23 pounds. Single recoil springs require that the Delta Elite recoil
spring guide be replaced with a standard 45 ACP recoil spring guide.
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.
