Wilson Combat's 17-pound flat-wire recoil spring kit for full-size 5-inch .45 ACP pistols. Improves cycling and extends spring life to approximately 40,000 rounds with standard and self-defense ammunition.
This is a purpose-built recoil spring system designed for the serious .45 ACP shooter who demands reliability and longevity from their equipment.

Wilson Combat's flat-wire design improves cycling consistency and overall pistol operation compared to conventional coil springs. The flat-wire geometry distributes force more evenly, reducing wear on the spring itself. You can expect approximately 40,000 rounds of service life before replacement becomes necessary—a significant advantage over standard springs.
This is the kind of upgrade that separates a well-maintained defensive or competition pistol from one that's merely functional.
