I am not at all surprised. I had a very similar experience with Wilson Combat a few years ago, and swore never to deal with them again. I bought a Compact version of the CQB from them. When I ordered it, they said it would take between eight months and a year, as they were back logged at the time. That was fine with me. About six weeks later, I get a call telling me that my CQB was ready for shipment and that they just needed the final payment. I asked how that could be, but the guy on the phone said it just was, without explaining why it was ready so soon when I was told at least eight months. I figured I wouldn't look a gift horse in the mouth and sent the check.
It arrived at the gun shop, and I came and picked it up. I looked at it in the shop, but it was dark and I was pretty eager to get it home, so I didn't notice the problems till I got it home. First off, the sights were the kind that were standard for the CQB from about two or three years previous. Since then, they had switched to Novak night sights. These had what I think were called "Cat Eye" sights, no longer part of the CQB package by this point. Next thing I noticed was that the finish looked like it had extensive holster wear on all the areas you get wear on a 1911 when it has been regularly carried for about a year. I immediately called them, and they just denied that it could have any wear on the finish, as they claimed the gun was just made brand new for me. Essentially, they were calling me a liar, so I figured I'd send it back and they could see for themselves, along with a note asking that they replace the sights and redo the finish (it looked like a well used gun). They sent it back to me with new sights, but the finish still looked like what you'd expect to see on a veteran carry gun. I called them, and they said the finish was fine, and they would not redo it at their expense.
I think I got a used demo gun. All the evidence is there. First, it was provided at least 6.5 months ahead of schedule. Second, it had the sights that had not been part of the CQB package for over two years by that time. Third, it's finish looked like it had been holstered daily for about a year, all forward corners having exposed metal, and a gradual fade from there to the areas with finish. I had never even holstered or fired the gun. That's the way it came to me. When I complained, their reps essentially laughed at me, as if to say, sue us. I would never buy another Wilson product again, short of a magazine.
