What caliber do you use in competition?

What competition?

Run and gun = 9MM/.40S&W/.45 Automatic depending on my mood.

Steel Challenge = .38 Super or 9MM

IDPA - SSP 40s&w
Esp - 9mm
USPSA - Production - 40s&w
Open - 9mm Major

I did not vote as it depends on the match in question.

Steel Challenge, I generally shoot a .22 and .45acp, although I am currently having an open gun built in 9mm.

ICORE. will be .38 special.

Take-5 .22

Local indoor match scored under ICORE scoring, but open to anything I have shot .22, .45 , .38spl and 9mm.

USPSA will be .45 ACP if I can ever get out to a match or 9mm.

Like many others, it would depend on what you're shooting.

Since I really only shoot USPSA, here's my thoughts. For Production, there's no benefit to shooting anything larger than 9mm since all is scored as Minor. 9mm is cheaper than .40, so why not?

If I was going to shoot Lim 10 (like I will be soon...4 more days to 1911! WOO) there is a disadvantage to shooting *most* 9mm as it doesn't make major. If that's the case, .40 or higher so you can score using major PF. (Like on Sat, Scorp, you may or may not have been better of in Lim 10 than Production.)
