Sig Sauer / GSG 1911 Main Spring Calibration Kit November 21, 2024 Reviewer: Edward Sanchez from Ladson, SC United States   The Sig Sauer / GSG 1911 Main Spring Calibration Kit was able to fix the lite primer strike issue my Sig Sauer 1911-22 was having. I'm still having issues with certain brands of .22LR amo, but the amo it does like, works reliably magazine after magazine. I recommend these springs if you are having lite primer strike issues.

New Mainspring for 1911 22 June 28, 2023 Reviewer: Joe Collins from Ewing, NJ United States   Having a problem with out of the box Sig/ATI/Mauser light strikes.  New 20 lb mainspring along with extended firing pin and enhanced recoil system seems to have corrected the issue.

Better tutorial would have been nice. July 28, 2021 Reviewer: Troy Hayes from Warrenton, VA United States   A better online tutorial would have helped me get the mainspring out of the mainspring housing.  Hence, a one-star ding. Was this review helpful to you?
