1. By the time you find and buy a 2" barrel, extractor rod, and center pin; and pay a gunsmith to properly install them, you will have spent nearly enough for a second gun. Maybe leave out the "nearly".
This really hits it on the head. You may find a model 10 snub for less than it would cost to convert. I am very unsentimental about these things, so I would probably just sell it and buy a concealed carry gun I liked, but others feel differently.
