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. Use Stock No. 490xx

 WARNING: Do not use shock buffers with these springs.

• Reduced Power...: 18.5 & 20 Lb.
• Factory Standard.: 22 Lb.
• Extra Power.........: 24 Lb.

Recoil Calibration Paks are offered to allow the shooter a choice of recoil springs to calibrate the recoil function when the correct spring rating is not known. These paks offer a savings of 20% over the same purchase of individual springs. The shooter starts with the strongest spring in the pak and works down until the desired recoil function is obtained.
