I have only competed in a few Steel Challenge and ane or two IDPA matches. The guys and gals with the Mega-High-Cap-with Holo-sight pistols and Team jerseys are awesome to watch.
But... do they carry that gun?
I shoot an old steel 1911 and I am nowhere near what they can do. In speed, anyway. I can hit those targets just fine; I just can't hit all ten of them (twice each) in four seconds.
So.... I have a realistic asessment of what I can do, on any given day, using my own EDC pistol.
That is worth far more than what someone else can do under contrived/controlled circumstances.
Some of the wisest words I have ever heard by on old engineer, and I may be mis-quoting him somewhat, but if you are a thinking man, you will get the idea:
In theory, theory and practice are the same.
In practice, they are different.
If that didn't get the message through, I will step it down a notch and quote Clint Eastwood:
A man's got to know his limitations.
Which is not to say that you should not strive to expand on those limitations...
