The notes on the work order said something like "adjust slide to frame fit, refinish slide". They didn't go into a lot of detail. I noticed that the slide to frame fit was much tighter after I got it back. Before there was quite a bit or horizontal play. There is no rubbing now. It's a keeper now.
The front sight looks a little different now too. There is a dimple on the top of the sight that is not on the orginal sight. I'm not sure what the difference is but it is solid now. The woman that I spoke to at Colt said they have been having problems with the sights falling off.
I would recommend giving any Colt a good look over before buying (of course I always recommend this for any brand). I also had a new Commander XSE that I bought at the same time. I had lots of failures with it and cosmetically it was horrible. It went back to Colt twice and was still not at all reliable. The third time back, they kept it and sent me a check.
With that said, I still want a commander and will probably buy another one.
