The preening is just the price of having an aluminium frame (the AL in PT1911AL). I can't say why some 1911s are particular about their diet, while others aren't, but I can almost garantee that the prior owner sold it because of that. Polish up the feed ramp and the lower lip of the chamber, and put a few hundred rounds through it for a proper break in period. If it still gives you FTFs after that, use the Taurus lifetime warranty.
