I can honestly say that my PT1911 is a "tack driver" right out of the box (I sprang $520.00 for mine) and IMHO worth far more than what I paid for it and didn't have to do anything to it to get it this way. I own a PT-92 and it's extremely accurate as well. I owned a PT140 and it wasn't worth it's weight in dung as far as groupings go. Personally, I think lemons roll off of ANY "mass production" line and my PT140 just happened to be one of them. Some day I may give it another try, but I think my next .40 cal will be an XD. Perhaps that's why I stake my life on my Glock G33. Glock Perfection.
