1911 & 2011 Recoil Spring Calibration Kit by Wolff

Recoil springs for Colt 1911 series pistols are available in both conventional and variable power designs. Please refer to our FAQ section for information on conventional vs. variable design. Each Wolff recoil spring for Colt pistols includes an extra power firing pin spring. Recoil Calibration Paks are available offering a range of spring weights to tune your pistols recoil function. All springs are produced from Wolff proprietary HTCS spring material except as noted.
The 3 most popular 1911 recoil springs are also available in chrome silicone material. While chrome silicone is an excellent material, it is a softer material and does not offer the tensile strength of our proprietary HTCS spring material (the material from which most of our springs are produced from). We now offer these spings due do customer requests.
