My Charter Arms PITBULL has nicks or machine marks in a lot of places. There is a nick in the barrel underlug on the left side, a nick on the top of the frame toward the rear sights, the frame window has nicks on both sides top and bottom. The finish isn't as nice as a Taurus 905 – the only Taurus revolver I look at are the Taurus 905s (which I do quite often) and I've never seen a Taurus 905 with as many tiny gouges or nicks in it as I've seen with this Charter Arms PITBULL. Here are some pics of the poor finish on this revolver.
The photos don't really do it justice, the nicks are a lot more obvious when you have the gun in your hand.
