Maybe this should go in the PCC topic. I'll let smarter folks then I decide that.
I've been involved with USPSA since the late 1980s. I don't post here much, in fact this is a new account. I've shot single stack, production and then open. Really loved open. But as age began to works its magic I started to notice ever increasing hand tremors. This effects so much of your life, you're signature makes you look like a physician and trying to use simple tools like a screwdriver an act of madness. Even tried a few pharmaceuticals made for this type of thing, no luck. Shooting Open was beginning to loose its luster and open sights on a limited gun weren't much better. I figured my USPSA days were done and its been a steady part of my life for a very long time. The last match I shot using the open gun was a steel challenge match and I could not get reliable hits on the steel. I withdrew after the first stage. I was pretty depressed.
So it occurred to me that this new PCC thing might be the solution. And I know this is a pistol sport but what if it worked. So I dropped a dime or 2 on a GMR15 and low and behold. I'm back, having fun and working on a whole new series of skills. The tremors are there, but you don't see them in the dot. I can shoot a steel challenge again. And I hate to admit it, its more fun then I thought it would be, maybe even more fun then the Open gun. Even my wife joined me and she is a die hard Open gun shooter.
My point is, when you see that guy running and gunning with a rifle in a pistol sport. He may have a real good reason. It may be the last chance, especially for older shooters. Thanks USPSA for keeping the hope and my game alive.
