Been shooting a while, just never shot any real competitions. I am going to try an IDPA match coming up at the end of July. Any suggestions for any types of training I should try at my indoor and/or outdoor ranges before the IDPA match? I'll use a Beretta 92 - 9mm - three 15 round magazines (is that enough?). Any comments on average distances, # of shots per target, running around before I shoot, etc??.... Any comments appreciated!! Thanks!
