My vote goes to the S&W M15 two inch. A K frame.
The adjustable sights are easier to use than any other
snub I've shot. Enough grip to hold on to. Decent
trigger too.

My younger son was making fist sized groups with
one at 100 yards a few years ago. I was hitting high
and right above the shoulder of the silhouette.

Too bad they aren't made any more. I'd buy a new
one, in stainless, as soon as I saw one.
