FWIW... I've been a practical pistol and 3 gun competitor since 1982, and estimate nearing 400,000 rounds...my 1911's have broken finger bushings, solid bushings, slide stops, total barrel failures, link breaks, plunger tube loosening, extractor failures... my Rem1100/1187... extractor break, interceptor latch break, gas ring break, multiple "tuning fork" break, shell lift pin break
I shoot a G34 and a Benelli M1S90....

and IIRC never a mechanical failure other than knocking an extended mag pad off the Glock and dumping rounds, spring and follower... I guess I'm a fan boy
