I shot 3 pistol disciplines for quite a few years, IDPA,USPSA and Cowboy Action. Also some 3 gun and combat matches thrown in. I saw so many safety violations and bad gun handling skills in USPSA that I quit shooting those matches. Rounds fired into the ground in front of the competitor, 1911's going full auto from "sear tweaking", guys muzzling folks because they didn't know how to draw, mistakes made because everybody needed to be "fast" etc.....I find IDPA much safer and the people are nicer. Everybody in USPSA seemed to just want to win no matter how much money they had to spend on nifty gear and raceguns. People in IDPA seem more congenial and willing to help each other. Now mind you, this was all out West, I haven't shot USPSA in Indiana. They may be a nicer class of people back here...lol
