The guy in the pics used a fine Arkansas stone and spent hours. I used a fine Cratex wheel on a Dremel and it went faster. The first one I did I was worried about taking off too much and I did it three times before I got it right.
I had access to some small punches that could cut shims with for the side to side slop in the action and after getting frustrated getting the shims to stay in place while I reassembled the trigger group I gave up on the shims.
