With Wolff’s Recoil Calibration Pak, there’s finally an easy way to get the springs you need to fine tune your 1911 to match your favorite load, while saving money in the long run.
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.
