I've owned one for about 10 years. Best $295 (that's the price I paid for it back then) I ever spent on a firearm.
I bought mine new in box with the WONDER finish. Out of the box it needed the feed ramp polished (did it by hand to save hundreds of rounds) and a heavier recoil spring - after that, the gun will handle any and all ammo I've put through it - all weights, all bullet profiles. On top of that, I shot one of the best .45 ACP groups I've ever shot, using mine with PMC match grade 230 FMJ ammo. 10 rounds through a 3/4" (edge to edge) hole, at 25 feet at an indoor range - standing off-hand. I wouldn't hesitate to trust my life to it. Lot's of good commentary on many forums.
