The other is a pre-lock M60 3" .357 with adjustable sights. It is a miserable beast to shoot but it is also incredibly accurate for its size and recoil. If you can hang onto it, manage the sights, and forget what a beating your hand is about to receive, it's capable of 2 inch 50 yard groups from a rest with Federal 125 grain JHP factory ammo. Because I don't like shooting it to sight it in again, I don't mess with lighter loads, I just hope not to pull the trigger.
I wish S&W would offer a half-lug 4" 686 or 586. I guess that means a 4" model 19 would be a good contender ... never owned one so that's just guess work.
