Everything depends on what you plan to do with it. The lighter the gun, the more recoil, especially with magnums. The shorter the barrel, the less sight radius and the louder the blast. But if your intent is concealed carry, small and light is the way to go. S&W just brought back the Model 66, one of the most popular revolvers of all time. It's a K-frame, which is mid-sized, lighter and easier to carry than the L-frame 686/586 or the N-frame 27/627. Any of the above and the comparable Rugers, or even Colts if you can find one, would be a good investment.
