Check out the S&W 340PD. Extremely light. Very-well suited to carry comfortably. These guns are not range toys; you're not going to be shooting hundred of rounds every weekend for the hell of it with it. Practice, certainly, but for this type of gun, comfort of shooting shouldn't really be a factor. It should be something comfortable to carry that stops a threat. Just my .02.
He said it pretty good there. But I did find that with using regular 158gr. (Rainier plated maybe? they work good at low velocity) .38 special, not +P, just run of the mill, even loaded toward the weak end of the spectrum, does lend for a decent practice round out of the 340PD. Where there is a will, there is a way. It has far less recoil, more like that of a +P or light magnum in an all stainless snub. Very manageable. Should have mentioned that, but I just stumbled upon it myself recently.
Maybe the solution here is to bring enough pocket? I imagine that if it's large enough you can shoehorn just about anything in there? My idea of pocket carry is usually limited to real mouse guns, .32 ACP or less. I've carried a 2" .38 Special J-frame (Model 36?) in the past, but like one of the posters upthread noted, its five round cylinder makes me feel like I "have a chance." I agree with the notion that it's quick to pull and easy to use in hammerless or shrouded configurations, especially given the effects of adrenaline, but I still hold with the idea of going with something that encourages practice and offers an easier reload.
I don't know, maybe? It fits in most of my pockets no problem, and no, I don't need a shoehorn to get it in or out, it goes in and out quite easy. It being scandium alloy and titanium, it doesn't weight much at all, and due to this it doesn't weigh down the pocket as I said and cause it to print nearly as much as stainless model (I've tried my wife's shrouded once and it was very heavy, printed, was harder to draw and it certainly weighed down the pocket).
I guess if you pocket carry a revolver, a stainless one, I'd consider a pocket holster too. Or just going IWB, that'd be infinitely better. I don't know how pocket holsters work out, but there is a market for them and Milt Sparks even makes 'em (thought about one of those, just to prevent wear --the front sight, over time, will wear the fabric in your pocket).
But if you want this for what I use mine for, summer carry in shorts or to the store or during other times as maybe a backup, really consider that 340PD and what I've told you above. You can practice with it, just not always using what you carry. It isn't a big deal for a snub like this.
If you consider carrying a revolver all the time, you may want to consider a 640 no lock or if you want the hammer, a 649 no lock like my wife carries. Then have it modified to accept half moon clips. Those'll be easier to conceal and carry than full ones, easier to load than so-called "speed loaders". Plan on having this done to ours.
BTW, reconsider your choice, if I may be so bold in saying so, bump it up to .357. You can still run .38+P's no problem, but have the added ability to use .357. They also retain resale value more. The aluminum airweight models get scratched easy and wear easy, and they are pretty snappy too with +P's. If you want the increase in weight, you can get the 340PD with a stainless cylinder to help reduce recoil and use +P's instead of mags. The custom shop may also have something interesting in looking at; call 'em. These are all just options.
I looked at some of the others yesterday, there a few .380's out now by good manufacturers, not sure of how well they hold up or handle personally, but they look real nice and are small. Still, not my cup of tea. I still love my 340PD for what it does.
Good luck!
PS, I did get a box of 135gr. Gold Dot +P short barrel to chrono... If it works out well and isn't punishing, I may switch to it. But I haven't found a +P that comes close to the mag, even out of a 2" or 1-7/8"bbl. Usually off by as much as 200-300fps.
