I wouldn't question his PPC ability. But a 1911 is a different beast.
And then, IMHO, the best smiths are the ones that specialize. Some folks don't get that, but I'd rather a smith that had done 100 1911s, than one that had done 10 of this and 10 of that. At least when we are talking top notch reliability and ACCURACY.
Being a competitor helps, of that discipline. But being that competitor doesn't alone guarantee worth a flip either.
Used to shoot with a guy that built service rifles. He shot them very well. They didn't shoot that well. Had he ever driven the ones I had built I think he might have surprised himself at how much better he could have been. But he claimed you coudl only use so much accuracy. So be it. I could stomp him consistenly once we left the 200 yard line. I could even him in sitting rapid, generally, and loose in standing. But prone rapid and prone slow were mine. And part of that was the guns ability.
