The Wilson Combat 18 lb recoil spring (brand part number 703G18) is built for full-size 5-inch 45 ACP 1911 pistols shooting 230 grain hardball-equivalent or standard-pressure JHP self-defense ammunition, with a power factor between 175,000 and 195,000. A fresh recoil spring is one of the cheapest ways to protect a 1911’s slide and frame, since a worn-out spring lets the slide slam home harder with every cycle. Wilson Combat rates this spring for an average service life of about 15,000 rounds, so replacing it on schedule keeps the pounding on your frame rails in check and helps preserve long-term reliability.
