If you're going to shoot at a club you've never been to before, try to get the info sooner than the day before the match. Otherwise you may find a deserted shooting range and find out the next day that the match was cancelled. It's ok, though, because I was going to shoot my first 100 reloads, and I shot them at the range instead and discovered I'm doing something wrong because about 20% of them didn't feed. I'd have embarassed myself terribly judo-chopping the mag floorplate every other round throughout five stages in front of a bunch of guys I don't know.
I've only got two hands, but I've been known to carry three Glocks.
