.357 Revolver
If stainless steel is not a must, I would look at the S&W M-28 "Highway Patrolman", it is basically an M-27 with a plainer "service" finish, N-frame, adjustable sights. I have a 6", plenty accurate, the heavy frame absorbs recoil better than a lighter frame (with proper grips of course). Not as visually
appealing as a Python or stainless S&W but as a wise old shooter told me years ago "You don't shoot bluing."
