I was a member of a gun club in England back about 15 years ago, and there was a guy there who in all honesty was a bit of a dickhead, anyway, one of the other problems with the early P226s was that some of the barrels were pretty loose. He told me he'd had his miked and it came in at just over .356", so he proudly sits there and tells me he's made his P226 more accurate by using .357" bullets in it.
He goes out on the range, and I hear: bang, bang, bang, BANG! And that was the end of his P226. I think the flaw in his logic was that his cast bullets in some cases were probably over .357" in diameter. Blew the grip panel off the right-hand side of the gun, trigger bar was bent, magazine blew out of the magazine well, the barrel bulged and jammed the slide. All things considered it could of been worse.
And then he bought a Taurus PT-92 and he also blew that up.
