The Wilson Combat Custom-Tune Spring Kit (Wilson Combat part no. 324G) is a complete spring upgrade built for full-size 1911 and Government-model .45 ACP pistols. Wilson Combat makes every spring in the kit from high-tensile wire for consistent function and long service life, then includes two recoil spring weights, a reduced-power mainspring, and an extra-power firing pin spring so a shooter can tune the pistol to their exact load and use case. The lighter recoil spring suits softer practice ammunition, while the heavier 18.5-pound spring keeps feeding reliable with full-power factory loads. Swapping in the reduced-power mainspring can cut trigger pull by up to 25 percent, and the extra-power firing pin spring adds both reliability and drop-safety margin.

Frequently Asked Questions

Will this fit a Commander-size 1911? No, this kit is built for full-size 1911/Government models, not the shorter Commander frame.

Which recoil spring should I use for daily carry ammo? The 18.5-pound extra-power spring is built for reliable feeding with full-power factory loads; the 10-pound spring is meant for lighter practice ammunition.

Does the reduced-power mainspring affect safety? No, it only reduces hammer spring tension to lighten trigger pull; it doesn’t affect the gun’s mechanical safeties.
