Kirk M. (in the blue jacket in this picture from the March set-up)has passed along this reminder: Spring is an excellent time to tune-up your pistol. Spend a little time and a few dollars and prevent your gun from failing in a match later.
Tear your gun down as far as possible and inspect for unusual wear and breakage. Repair and replace parts as necessary. Replace springs whether they need or not. Springs wear out with no visible sign or warning. One day they work the next they don't. You should replace at least your recoil spring, mainspring, sear spring, firing pin spring and all of your magazine springs. This is not a terribly expensive endeavor when you consider what the matches cost that you could be trashing this summer.
