Stainless steel is great. It holds a polish nearly for ever. It holds scratches nearly forever too. After a good buffing, a dull factory hammer comes up to a mirror shine and is ready for jeweling.
And a simple but functional modification to the loading gate. Its a thick chunk of metal....rather like an acorn with a hinge. A bit of work on the backside makes room for the thumb to be inserted and flip the gate open. Its not a visible modification, just one that helps guide the thumb in to place to positively get it open....its nice when you are wearing gloves on a cold day.
