Wilson Combat Custom-Tune Spring Kit for 1911 Government Pistols

The Wilson Combat Custom-Tune Spring Kit for 1911 Government Pistols is a set of precision replacement springs engineered to restore reliable cycling and function to your .45 ACP. If your 1911 Government has seen hard use or you're rebuilding a pistol, swapping worn springs for fresh, high-tensile-strength components is one of the smartest tuning moves you can make—and it's straightforward enough for any shooter comfortable with basic handgun maintenance.

This kit includes everything you need for a complete spring refresh: a 19 lb. hammer spring (RP spec), an XP firing pin spring, and your choice of recoil springs in both 10 lb. (RP) and 18½ lb. (XP) weights. The high-tensile wire construction resists fatigue and maintains consistent performance shot after shot. Whether you're running competition loads, hunting loads, or standard .45 ACP ammunition, having the right spring weights on hand lets you fine-tune your gun's function to your specific round and slide speed.

Wilson Combat springs are trusted by serious 1911 shooters—gunsmiths, competitors, and hunters—because they're manufactured to exacting standards and actually solve real reliability problems rather than just repackage generic parts. This kit takes the guesswork out of spring selection for the most common 1911 platform.

Frequently Asked Questions

Will this spring kit work on my Colt 1911 Government?

Yes. This kit is designed specifically for 1911 Government models chambered in .45 ACP and includes the appropriate hammer and recoil spring weights for that platform.

What do the different recoil spring weights do?

Recoil spring weight affects how quickly the slide returns to battery. The lighter 10 lb. spring (RP) cycles faster and is suitable for softer-shooting loads, while the heavier 18½ lb. spring (XP) works better with full-power ammunition and competitive loads. Having both gives you flexibility to match your ammo.

Can I install these springs myself?

These are drop-in replacement springs designed for standard 1911 takedown and reassembly. If you're comfortable field-stripping your pistol, you can swap them. If you're unsure, a local gunsmith can install them quickly.

Why replace springs if my 1911 runs fine?

Springs fatigue over time and lose tension, even if function seems normal. Fresh, high-quality springs from Wilson Combat restore crisp trigger reset, reliable firing pin strike, and consistent slide cycling—especially important if your pistol has seen heavy use or you're running different ammunition weights than the gun was set up for originally.
