I've never shot an IDPA match but I've shot Tuesday Night Steel matches out here and back east I shot a lot of steel plate rack matches. Tuesday night steel here utilizes steel targets from 12 feet out to as much as 30 feet.
I use two handed Quick Kill almost exclusively in these matches, along with moving in and out of front sight press and full sight picture and back to the Quick Kill depending on the precision of the shot necessary and the distances to the steel, all two handed shooting sometimes from Iso and sometimes using a modified Weaver stance depending on where my feet are placed by turreting my upper body.
Using all the above, I usually will score higher at the end of the night than 8-9 master class shooters and 2-3 grandmaster shooters. I'm just a D class shooter on the score cards and haven't shot enough matches to move higher in the rankings.
I specifically signed on to the steel matches to see how my Quick Kill skills would work against exclusive front sight pressers. Obviously I have faster stages than many of the gamers using Quick Kill peripheral vision skills and that's what I wanted to prove to others and myself. I'd probably get better in the standings still if I ran the matches and learned how to game them as others who shoot them regularly do. I didn't bother doing that, for in the real world you don't get to look over the course of fire and develop a game plan to get the best time.
Another situation that's problematic in the games is the idea of shooting from "boxes" or "stations" which aren't laid out in the real world either. Moving to and from areas within a stage, I'd be shooting while moving and not wait to get to some specific point or be disqualified or penalized.
Just this weekend while putting on the pistol class in Howie in the Hills, one of the students who shoots a lot of IDPA was asked to solve a two threat problem at 8 feet his way which he kind enough to step up and do for us using a two hand hold at or near line of sight. I then showed him quick kill hip and had both threats shot before he'd shot the first threat. I could see the light bulbs go off and it was nothing more than to prove that some skilll are superior in speed than others and one must understand when to use what skill to their advantage.
I like the games for what they are. They get people to shoot and gain superior gun handling skills over time. Too many people don't have even those skills ingrained and the little stress created by the timer can be a good experience at well. One must stay focused and solve the problem even when the heart rate is increased for some reason.
