Pitting........ you ain't seen real pitting on pistols yet! It's a military pistol and that's how they get........ rusty and pitted. We used to see them like that every day of the week. In the tropics and salt water swamps they were pitting from day 1 Through the bead blaster to remove and neutralise the rust, phosphate (or chemically black, your choice) and you've got a perfectly satisfactory pistol again. No concourse prizes but a) looks a zillion times better than it did, b) it ain't going to rust no more and c) worth a lot more too
