Just out of curiosity, how many folks wear the same clothing and shoes at matches as they do when they are CCWing? In 6 years of shooting IDPA, I only saw one person show up in a suit.
I carry a little snub in my pocket every say. I also own a Glock 17, a 1911, and several revolvers. When I shoot IDPA, I shoot whatever gun I have picked out to compete with. My holsters are IDPA legal, and I range from IWB to belt holsters. I have about .5 seconds difference between the IWB and other holsters. Not much to cry over in my opinion.
I sense a recurring theme in all the threads, IDPA is a game. The rule book states that it is not intended as training, even though many of us use the matches to test theories or whatever we learned in a class, or even things we read about on the internet.
The best advise I can give you is, pick a path, and have fun with it. If you want to be one of the tacital teds, get your gear, and shoot the matches, talk over you theories with guys on the range, and have fun. If you want to be uber-competitive, get your gear, talk over your theories with guys on the range, and have fun.
