I bought a Beretta Xtrema a while ago. Had the gun for a few months and shot some 3 1/2" rounds thru it. I noticed a scratch running down the bore and could not get it out by cleaning the gun no matter what I tried . Sent it in to Beretta and it came back in 3 weeks untouched. They told me the gun was within specs and that it was just the chrome plating removed....I guess they didn't want to replace an almost 500 dollar barrel because of cosmetic purposes. To me it was a faulty plating job. I don't own the gun anymore.
