Get off your high horse and circulate among the people you're apparently looking down on, Dave. I don't know why you think I was putting Tucson -- or you -- down. I wasn't.
I don't know what goes on in Tucson, but it sounds as if the "gamers/snobs" have taken over your IDPA matches -- the ones who no longer look at IDPA as practice for carrying their CCWs, but look only at it as another form of sport to be conquored to their whims, not unlike sporting clays, PPC, IPSC, etc.
Luckily the group I shoot IDPA occasionally hasn't fallen to that mindset yet.
When I get to a match (which isn't frequently enough) it's a toss up whether I'm going to be shooting my S&W 042 .38 Spl. or my Model 19 2.5" .357 Mag. But I'm not the only one who shows up with the little guns, and I'm certainly not the best of the crop.
One thing I do know, though, is that there's no lack of small J and K frame and the like revolvers at the matches. But, I guess since you were a founder in Tucson, you know better than anyone what's being shot in Virginia, and how well people a continent-width away can shoot the guns they choose to carry.
Luckily, the group I shoot with seems to be less concerned about power factor rules (is the skell who tries to stick a knife in your gut worried about power factors, or is that more BS artificality thought up by the "gamer/snobs" and designed to exclude certain shooters and guns from the events, or is Mr. Skell going to be more impressed with you sticking a couple slugs in his sorry criminal ass?) and more about practical application of marksmanship and gun handling.
When I shoot these matches, I shoot my carry ammo or handloads designed to emulate my carry ammo -- in .38 it's 125-gr. +P, in .357 it's 125-gr. Remington Gold Dot.
Other times I may take my Kahr. One of these days I'm going to shoot it with my Taurus PT-22.
But, since you do apparently know all, please tell me which gun I'm planning on shooting at the next IDPA event I attend?
