My father and I just picked up new FNP45s and while cleaning them today we noticed a small ridge in one of the grooves of the barrel. Not quite sure if it will effect accuracy or not as I'm new to the autoloaders, so what do you guys think?

I tried taking a picture of it the best as I could, and believe they are decent enough to see what I'm talking about.

Both mine and my fathers have this ridge in the same groove and the dates of which they were test fired are about 8 months apart. Didn't seem to hurt anything as they were an absolute blast to shoot yesterday. We love these things!

Has anyone else seen this?





I inverted and changed some things to try to make it more visible in this picture...

Do you have a barrel light or a fiber optic rod to illuminate the barrel, because that might help make it visible.

I've never seen a ridge. Can you feel it with a pick or anything?

I took some more pics. This is of my fathers' barrel, and it appears to be more definate than mine.

I could not feel the ridge on my barrel with pick, and I haven't tried feeling my fathers' barrel yet.

Is that the end of the barrel or the chamber area? I wonder if it is from some part of the manufacturing process. I don't think I'd worry about it if I couldn't feel it with a pick, but your fathers looks like there is a dent in it.

I have an HK P7M8 with a couple spots like that at the end of the barrel; you can even feel it a little with a pick. I sent it back and they looked at it, shot it, and said it was fine.

Seems to shoot good enough.

I'd say "Good eye, but don't sweat it".

I don't believe it to be carbon as it won't scrap off with a pick. We each fired 2 mags (28 rounds) then cleaned them. I didn't notice it during the pre-fire cleaning, but the post-fire cleaning is where I noticed them.

The fact that they are both in the same spot in the same groove on the chamber end of the barrel makes me think it's a manufacturing process tooling mark.

No complaints here, just curious if anyone has noticed.

Still shoots just fine. :shock:
