The Wilson Combat Flat-Wire Recoil Spring Kit (brand part number 614) is a 17-pound spring built for full-size, 5-inch .45 ACP 1911s running 230-grain hardball-equivalent or standard-pressure JHP self-defense loads with a power factor between 175,000 and 195,000. Flat-wire construction improves cycling and overall operation compared to a factory round-wire spring, and Wilson Combat rates the average service life at around 40,000 rounds before it needs replacing.
