My only 1911 is a Taurus which I purchased last year. It has nearly a thousnd rounds through it and runs reliably as well as shoots accurately. I did have feeding problems when I first started loading for it - I was running the reincarnation of the flying ashtray. Ball has never givien me problems - lead or jacketed - and XTPs seem to feed well. Your 1911 my vary, I don't think we can speak generally about the 1911.
