As a law enforcement firearms instructor since 1980, I've carried a few revolvers in my day, and continue to do so. A revolver is a good choice for an EDC gun. Yes, it has limited capacity, and can be slower to reload than a semi-auto, BUT unless you are headed for Afghanistan, the chances of you needing more than the standard capacity revolver is very slim. Usually even if you encounter multiple subjects, when the first round is fired, they tend to run more than fight. (Of course I'm not discounting the fact you could be targeted for attack by two dozen ninjas.)
I tell my students to find a handgun that feels good to them and they can shoot accurately. If that's a .44 magnum, great. Reality wise, when it comes to handguns, bullet placement is everything. You can not make up for poor marksmanship with a bigger caliber. A smaller framed .357 Magnum in an actual shooting scenario, is likely to be less effective than the same gun loaded with .38 Spl short barreled ammunition. I say this because the recoil and muzzle flash will be much less than the .357 Magnum, which will make for quicker and more accurate follow-on shots if necessary.
You also need to remember the 50% rule. That is no matter how tight a group you shoot on the target range, in a real armed encounter, your group will be at least 50% larger. Unless you are someone who shoots and trains constantly, this is a reality. So plan accordingly.
So if you are looking for a new EDC revolver, I would suggest a S&W J frame revolver in .38 Spl., hammer or internal hammer your choice. I would also look at a Colt Cobra or Night Cobra, or even an older Detective Special. Ruger SP-101. IMHO all good choices.
