Wolff 1911 Commander Recoil Spring Pack Extra Power

Recoil Calibration Packs are offered to allow the shooter a choice of recoil springs to calibrate the recoil function when the correct spring rating is not known. The shooter starts with the strongest spring and works down until the desired recoil function is obtained. Each Pak contains several recoil springs and offers a savings over buying them individually, including 18, 20, 22, 24 and 26 lb springs. Three extra power firing pin/striker springs are also included.
