Not a revolver, but the 4.5" barreled S&W 422/622 alloy frame semi-autos with adjustable sights carry better for me than comparable revolvers.
Good choice.
Funny, but the OP says "lightweight" and folks respond with all steel revolvers.
I have a 6" 622 (circa 1992) and it is certainly meets the lightweight criteria. Nice plinker.
I wouldn't screw around with revolvers personally as there too many lightweight semi-autos to ignore.
