Barrel finish chip - is this a problem?
I've put about 450 rounds through my new G19 and noticed today while cleaning that the black finishing or maybe Tenifer treatment seems to have chipped. A picture is below. This is my first firearm and I wanted to ask a few questions for the experts:
1. Will this affect the functioning of the firearm?
2. Is this a chip in the finishing or the Tenifer itself? I'm wondering about longevity and resistance to rust. If just finish, no issues there.
3. Is this common? Are there others that have similar nicks/chips?
Thank you for any help!
