OK, I'll play. Kind of embarrassing now though.
Started out a 10-5 from Century Arms, delivered to my door for $127.00. It was 1992, I had a FFL, extra money and extra time. I got all the parts from Brownells, (as well as all the tools I soon found out I needed.) I made my own frame support for a vice, took the barrel off and went to town on the inside. I sure learned a lot, and found out how to do a superb trigger job on S&W revolvers.
I sent all of the disassembled parts out for hard chroming, then fit the barrel and put it back together. It has thousands of rounds through it now, and is still perfect, although very dated.
