I am at around 1500-2000 rounds (lets see 50 rounds per box times 30-40 boxes?? yep!) anyway just as tight and pretty as the day i cleaned it the first time.
Big Skiff is north of 10,000 rounds in his and no reported problems.
seems a lot of you Pt1911 guys need to quit posting so much and get out there and do some shooting!-Griiin.
