no pics other than stock photo but I specifically asked if the picture was a good example of how they look and he told me yes and that he would pick a nice one out. So I have to ask myself , if this is a nice one I would hate to see a bad one. STock photo was here.
And after a couple hours of cleaning it looks better but I will take a pic in a bit and see what you guys think.
IMO, the seller used deceptive language and photo. To me, that is not 'light' holster wear, it is significant holster wear. And that photo is not a 'good example' that shows where this 'light' holster wear is on that gun. Not only is there the mark on the slide, but the finish on your blued hardware and sights is also worn...
That being said, it's not horrible, and you've gotten some good advice on how to fix the area on the slide that's worn. Hopefully, the gun is a carried a lot, and shot a little gun, and is otherwise in great shape.
If the deal was one where the seller has a bunch of LEO trade in guns, and he just uses general description/photo for the lot of them, then it is what it is, and I don't blame the seller if he states that conditions vary. Usually, you're getting a decent price, and luck of the draw on the exact condition of the gun that you may receive.
I used to buy quite a few guns on gunbroker, Guns America, and forums, and for the most part did pretty well, with no major problems. In my experience, the problems are with lack of disclosure on minor finish issues.
Example is where the seller does not show a photo of an area of the gun that has a defect, or finish issue. Or shows photos that really hide the overall condition of the gun, like the one in this thread (over exposed light really washes out the gun...).
Happened to me with a Colt Woodsman I bought on GB. Gun was in nice shape, but the seller didn't disclose/show a significant blemish on the rear blackstrap of the gun. It's a rust spot the size of a pencil eraser, maybe a little smaller. Not the end of the world, but certainly should have been disclosed, it is noticeable. Some people have no ethics, and lie by omission. Makes you kind of want to reach out and whack these types in the head a few times in an effort to straighten them out, but hey, I'm a peace-loving kind of guy...

I've mainly had good experiences with online gun purchases where the sellers were very conscientious regarding their reputation as a seller, and making sure to provide good pictures and an accurate description. You learn to look for certain things from a seller. But, unfortunately, there are a lot of unethical people out there, just have to be careful, and be willing to be patient/walk away if it does not feel right.
OP, at the end of the day, it looks like you'll have a nice carry gun, for a decent price. If it continues to bother you, you can always sell it and get one in the condition that you really want...
