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.

Recoil Springs - 1911 Longslide Modifications
Longslide modifications to 1911 pistols often require a longer than normal recoil spring. Wolff longslide recoil springs are designed for use in pistols with recoil spaces up to 3" (when slide is in full recoil position). 5 different strength recoil springs are available denoted as #1 thru #5. Due to the custom nature of these modifications, no rating for these springs is possible. The #1 recoil spring is the strongest and #5 is the lightest. Fitting of these springs is required. Professional installation suggested.

Magazine Springs
Magazine springs for the above Colt pistols are available in a variety of load ratings to accommodate almost any shooting requirement.
Extra power (XP) magazine springs are recommended for use with full power loads especially when using extra power recoil springs. Extra power magazine springs assure smooth feeding and proper cartridge seating. In addition to the traditional extra power magazine springs.
Reduced power (RP) magazine springs are available for Colt pistols. These springs are intended for use only with compensated pistols and/or with very light ammunition loads. Reduced power magazine springs lessen the cartridge pressure on the underside of the slide to improve functioning in low recoil energy situations.
Use of reduced power magazine springs with full power ammunition will cause functioning problems.
Please note: load ratings indicated are with the magazine fully loaded.

Firing Pin Springs
Wolff Extra Power firing pin springs are a must in Colt pistols prior to the inclusion of the firing pin safety mechanism and are highly recommended in all pistols. These springs are approximately 40% stronger than the factory springs and provide an increased margin of safety by helping to reduce the chance of accidental discharge due to the firing pin contacting the cartridge primer in the event of dropping the pistol in a loaded condition or from the increased inertia imposed on the firing pin with extra power recoil springs. Every Colt pistol should have an extra power firing pin spring installed even when shooting the lightest loads. All Wolff load-rated Colt recoil springs are packaged with this spring. Original factory springs are also available.
In addition, we now offer Extra Extra Power firing pin springs. These springs are approximately 85% stronger than original factory firing pin springs. These springs are used to provide a greater margin of safety, particularly when trying to meet certain drop test requirements.
For use in:
Colt 1911, 1911A1, 1991, Government, MKIV, Gold Cup, Commander in .45, super .38 and 9mm, Officer's Model .45 and Delta Elite 10mm.
