I was out & about yesterday,, loafing in gun shops, pawn shops, & thrift stores. I found a Glock, OEM 31 round mag for $20. I'm going to try it out.
Snake,, you might look into USPSA dot org to see what it's all about. At clubs all across the country, they design, build & shoot "stages" that challenge you mentally & physically. There are (8) firearm categories, and (7) classifications of shooters. Then, there are divisions such as Junior, LEO, Senior, or Super Senior.
Basically, you can be any kind of shooter & compete against folks using similar firearms, with similar abilities.
But what it does do, is allow a person to work on their personal skills. Accuracy, speed, thinking, reacting, dealing with gun problems, etc. In general, you are training your body to have "motor memory skills." Same as many things we do daily.
But if you want to be competitive within your division, & classification, you want your equipment to be of quality & reliably function.
