A fellow shooter e-mailed these images of Brian shooting in the 2008 IDPA Nevada State Championship:

IDPA and USPSA share a lot in common. The same safety rules and operating procedures, for example. The main differences, other than restricting the limited/open type guns, are that you have to shoot from behind, over, around, or under cover.   That and you can’t drop magazines with bullets left in them.  A lot of stages have you shooting while moving backwards (the idea being to avoid whatever is threatening you).

Brian and I shoot IDPA monthly in Las Vegas. If you want to tag along, just holler, we’ve got room for 3 other shooters to go with us.
