Can someone tell me how to determine the correct recoil spring Power(?) for a 1948 vintage 1911 38 super. It will be used with +P loads and reloaded equivalents. Thanks for any help...captn-tin

recoil spring

14lbs is standard weight for a government model 38 super. 9mm is 11-14lbs with 40s&w being 17lbs. Hope that info helps.

The primary job of the recoil spring is to strip the next round out of the magazine and properly chamber it.

so start at 14 and maybe go higher if shooting +P.

Recoil Springs
For Use in:
Colt 1911, 1911A1, 1991, Government, MKIV and Gold Cup models
Please see other caliber notes below



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.
