Ruger SP101. Rough, tough, rugged. Will take a diet of full power .357s and ask for more. Is controllable with full power .357s, and is a ton of real fun to shoot with .38s, even +Ps. It's not as light as some, but that weight contributes to it's controllability. Compact carry gun on the belt, or IWB, fast out of the holster. Simply an awesome gun. Mine was a 3", which I highly recommend.
You beat me to it Mr. Williams. The sp101 gets my vote also.
