The Wilson Combat Flat Wire Recoil Spring Kit (Wilson Combat part no. 651) is sized for the mid-size Commander 1911 frame’s 4-inch barrel and built from flat wire rather than traditional round wire. Wilson Combat is one of the most respected names in match-grade 1911 pistolsmithing, and a flat wire spring compresses more consistently and typically holds its rated tension longer than a round wire spring of the same weight, which can mean smoother, more predictable cycling over the spring’s service life.
