Wolff COLT 1911 .45 RP RECOIL CALIBRATION PAK
Recoil Calibration Paks
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 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.

Stock No. 13112 – Reduced Power Pak – Conventional
