I purchased a new CZ75 SP-01 yesterday, this was my third bucket list gun, now I'm done! When I field stripped the gun to give it a good cleaning , I noticed the barrel coating had a lot off wear for a new gun. I called the LGS and asked it it was used and was told no, factory new. The only gun I have that has that kind of wear is my SIG P226 Mk25, it has 1000 rounds thru her. Is it normal for CZ metal pistols to have wear on the barrel?
