Working on a Smith & Wesson 686 right now.  These are so fun.  They were made right and you can really achieve a lot out of them.  The slop that is so common in revolvers of the modern vintage is not there.  Certainly I work on all the new stuff, but you can tell the difference in the older guns. What should you buy?  I’m glad you asked.  If you want a gun that is going to be able to be worked up to a great level, get an older Smith...
