I carry a Taurus snubby fairly often, especially in the summer. .357 5-shot. It's been a great gun, and is surprisingly accurate.
If I was looking for something bigger, my next pick would be (as an above poster mentioned) a Ruger GP-100. They are fun to shoot (the small Taurus is not), comfortable in the hand, and made to last forever + one week. I loved mine, and plan on buying another one soon.
