Second: especially when there's some emotional attachment.
The rebuilt Kimber frame worked perfectly, with the .22 conversion on top it went through about a hundred rounds without a single problem. I'll have more on this later, want to take a couple of pictures for that report.
The other was a Smith & Wesson revolver given to me by someone. It's a .357 that has a LOT of wear on it, and had developed a couple of problems. Working fine now. More on that later as well, with a couple of pictures.
