In addition to the 3" Model 657 seen above, I'll carry a 4" 629-4 .44 Magnum or a 27-3 .357 Magnum on occasion. N Frames fit my hand well, I shoot them pretty well, and I just plain like them. If you can conceal an N-Frame, why would you not carry one?
BTW - I don't understand why dla dislikes the .44 magnum cartridge. It is extremely versatile, and is a very effective self defense round. Short of a rifle, the .44 does a credible job.
Yes, when it is loaded to it's potential it is quite the round. But when it is downloaded it is no more than a bulky, heavy .357mag or 45acp.
I like the 44mag and I shoot it a lot. But I have other carry weapons that are far superior to a 6 shot N-Frame.
