As Noted

RECOIL SPRINGS from W. C. Wolff Company for the Colt Officer's Model series 80, are a single recoil spring design which replaces the original dual springs. The single recoil spring offers superior performance over dual springs which have a normal tendency to bind against each other as well as having a "mushy" feeling. The single spring offers crisp and reliable operation not usually found in dual spring systems. As with all Wolff load-rated recoil springs an extra power firing pin spring is included.

Full Diameter recoil springs are also for use in the Kimber Compact, Para-Ordnance P-12 and Springfield Untra Compact & V10 and the Colt Officers with full diameter/full length guide rods

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 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 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.

For use in:
Colt 1911, 1911A1, 1991, Government, MKIV, Gold Cup, Commander and Officer's Model series pistols - Select appropriate caliber.
