I'm thinking of going the EXACT same route ... for the same reasons.
I LOVE my p226 but it seems so LARGE (especially since I've never EVER carried before).
Heck, I almost never even wear a BELT ... the idea of grabbing my phone, keys AND strapping on a big hunk of metal when I leave my home seems ... cumbersome, to say the least.
Slipping a smaller, light aluminum thing in my pocket seems a lot more feasible for me.
Still mulling it over, though.
It'll depend on your build and clothing style.
I found a full size Glock 17, with the right IWB holster/belt, conceals fine on me with a black tank top tucked in to keep the gun off my skin and match the holster/gun's color in the event the T shirt hikes up, and an untucked t shirt one size large hid the whole thing fine with hardly any print( especially if you use ther 45 degree "FBI rake").
Worked well today with even a crappy IWB holster( temporary till my holster is made) and a sweatshirt today.
And the Smith MP45 is not noticeably wider than the Glock was.
But maybe I don't wanna wear an untucked shirt, BDU blouse or other belt covering concealing garment, or maybe i have to dress somewhat nice for whatever reason.
Pocket holsters are your friend and can break up the snubbie's print and keep the trigger covered, but any good one will stay in the pocket when the snubbie is drawn.
No problems with sitting down, It doesn't interfere with social hugging such as at a family gathering, you can merely put your hand casually in your pocket if you twig that something's wrong--there is no faster draw than having your hand already on your gun, in such a way as not to even alert the sheeple.
If you have done the smart thing and gotten an enclosed, hammerless model(Such as the Smith 642), you need not even draw from your coat/sweatshirt/whatever pocket--there is no slide or hammer to catch on anything--the hammerless snubbie goes bang once in the pocket, it will go bang the next 4. Autos are only good for 1 in that instance and don't respond well to carry in sometimes gritty pockets if anything works its way into the slide.
But Be Warned:
*Do not expect ANYTHING like the accuracy you can expect from your full size SIG. I am happy to get all five shots into a roughly rib-cage/torso size area at 7 yds/21 ft and that's using BOTH hands. This is not a "target" gun, it's a "GET OFF ME!" gun.
*I can handle 38+Ps in mine but I'm not very recoil sensitive. FInd out where your comfort zone is with the airweight guns before you load them for carry.
*If you DO decide to go with a .357 snubbie, I STRONGLY recommend an all-steel gun, no alloy. Trust me on this one. No, really.
Since it may be carried as a backup to your fullsize auto, my common practice is to carry it in my left pocket:
*there's a gun in reach of either hand if my primary hand is wounded
* I therefore do much of my practice with the snubbie one handed with my left hand. That's how you live if hit in your good side.
If carried alone it matters not which pocket but practice from both so as not to get trapped by one-side-only muscle memory.
