What a wonderful pistol! A body would be proud to be seen with it. Fit and finish are remarkable.
One question - the markings on the barrel? I can state that I have seen random "pecking" marks, but they were on a tree and done by a woodpecker. Not poking fun at you - I am sure that they are there for a reason. Pretty nifty, really.
Go get them bars! You got the perfect tool for the job!
