I'll have to agree with JayDubya. This thread has been dominated by discussion of automatic pistols, but that doesn't make sense. I long ago concluded that strong-side front pocket carry provided so many tactical advantages that any other concealed carry mode was out of the question. And I carried a small automatic pistol for years (P-32). Late in life, I discovered that an aluminum-frame snub-nose .38 was virtually as concealable as the tiny automatic despite the fact that it was much bigger and was chambered for a much more powerful caliber. I've pocket carried a few automatics (Guardian 32, P-32, Mil-Pro, Bersa 380), but I always went back to the P-32--until I gave the snub-nose a try.
You can pocket carry a small automatic like a Bersa with a good enough holster (DeSantis Superfly), but I don't want to go through life with something like a small dictionary in my pocket. You're perfectly legal but there's a quality of life issue.
The snub-nose .38 is not an easy gun to shoot well. But if you're willing to practice, it will serve you admirably. Make sure you practice reloading the gun, too, because this is harder than with an automatic and requires more skill if you're going to do it quickly.
