I would have opted for the "L" frame for magnum use...though my first issued firearm was a S&W 65, .38 spc (bull barrel with fixed sights). My first revolver (personal) was a model 66 with micro-click adjustable rear/red ramp front sights, .357 magnum.
I blue-carded the .357 to my former bride. I currently carry a little S&W airweight five shot hammerless revolver, .38 spc, on my vest. I feed it +p ammo (Winchester Silvertip HP), 'cause chances are you'll only use it once...
Revolvers are still the "coolest"...and when it comes to automatics: 1911 rules, Glock/Sig/Berretta et al drools. period.
