Last one I had was stainless and it was 550. That's been a few years ago. Had bought a blued one for a frfiend as a gift and it was 500..Also a few years ago.
..So yeah, you got a good price.
They are pretty nice pistols. Especially for the price. I don't care for the plastic grips but truth be told I dislike most factory grips so it's nothing to look down on the pistol for.
The stainless one I had I literally shot the crap out of it. I would not cleanit for a long period of time to see when it would start to screw up. And, it always did really well. Well, till about 700 rounds then it would start getting a little squirrelly. That was dependent on he ammo though. Winchester bulk was more dirty than some of my target reloads. With my stuff I could get to 1K rounds without a problem. Even then it was a quick pull with a bore snake and a little oil on the rails and off I'd go again. My reason for doing it was the bad stories I kept hearing so I wanted to see just how much I could abuse it nad it still work right. On the downside it was a real chore to clean it after all that
The only problem I sen out of any PT1911 was the ambi safety on a few I had seen tried to work out over time. Put a good tap on them to set them again and they didn't do it a second time. So I figured maybe some of them where not set up good at the start. If that's the worst I would have to deal with I still would have no trouble buying another one.
