There is no barrel wear on the top where it is contacted by the slide (only a little where the barrel flares to lock against the slide, which is the slight ring just back from the muzzle), which tells me there haven't been many rounds through the gun. Yet there is chipping on the end of the guide rod, and the side of the rod (facing up in the picture) is excessively worn. It basically uses the same support design as a Glock, so the wear patterns should be similar. It almost seems the slide alignment is off, there is a burr, or a particulate is trapped.
Pointman,
There is actually no wear at all on the side of the guide rod - its just the way light reflected of it. As for the chipping on the end of the rod, i am not quite sure what exactly you are refering to. If that is about the whitish ring where the smaller diameter part of the rod penetrates into the larger diameter part, than its not chipping, its some kind of lubricant they used before shipping and i just wiped it off with a rag. Pictures are far from perfect and i was trying to focus my camera on the inside of the barrel, so stuff around it came out funny. Again, the only wear on the guide rod is on the inside end of it, where it presses against the barrel locking lug (you cant see it on the picture as it is inside the slide). Correct me if i am wrong

| Fantastic news. That is a problem with pictures not being 3-D. Glad everything is in good shape!

12:40AM EST: I just bought an XD-45 about ten days ago. I am going to check it right now for similar issues.
12:44AM EST: Okay, I've just inspected the barrel and I've got similar markings. I was just out today, so I'm going to clean it and see what it looks like afterward.
UPDATE: 1:47AM EST: Well, I cleaned it up and none of the "markings" came off. I am not particularly concerned about it as I've already thrown quite a few rounds down the barrel without any problem whatsoever other than a solitary feed problem. I could probably do a better job scrubbing at it, but again, I'm not particularly concerned about it.

Yeah, same thing happened with my brand new Glock 21 I bought last month. I fired only 10 rounds so far + factory testing, and the irony is I cleaned the barrel twice since. It has the same brownish marks along the bore grooves.
No oil I have here helps, nor does the nylon brush. I'm pretty sure it will go Kb! after a couple of hundred of rounds if this goes on. Any suggestion, guys? How dangerous this is?

I also have the same copper marks in my brand new G21 and 1911 after a trip to the range that put boxes of ammunition through it. As long as you're using jacketed ammunition in a G21, and the copper marks suggest you are, there shouldn't be cause for concern about a barrel explosion due to minimal copper fouling. Simply clean the barrel as I previously suggested and the copper will be dissolved.Attached Image (viewed 144 times):
