Just one: in the early/mid 90s I bought a 2 1/2" S&W 66 and by the late 90s to early oughts I sold it.
I have no memory as to why, I don't think I needed extra money for any reason so I can't figure out why I would get rid of this revolver.
It balanced perfectly, the trigger was smooth, it was accurate, it was just right (as all K frames seem to be).
I will get another, just not yet.
