All of those guns you mentioned seem way to big for pocket carry.
Depends on the size of your pockets.LOL. I've actually carried my G30 in the pocket of my jean shorts but those pockets are pretty good size.
I'd think for "normal" pocket size something like the Ruger LCP would work out ok. Just be aware that you'll be dealing with a 380acp so you'll not have the "punch" that you normally would in even a small holster gun like a Glock G26 or G27.
Personally I'd rather find a small gun that I shoot well(pocket size or not) and then adapt my carry methods to it rather then trying to find a gun that will fit into the carry method that I want to use.
I had a S&W 642, 38spl +P Airweight, sweet little gun to carry, had DeSantis Clip Grips on it so I could IWB without the need for a holster, didn't even know it was there most of the time. Problem was I had trouble keeping 5 shots on a 8"x12" piece of notebook paper at 7 yards. I can cut 1"-1.5" groups for 10 shots out of my G30 at that range and with a good IWB holster it's just as easy to carry and I've bumped up from 38spl to 45acp to boot.
I think it's easier to get the gun that you shoot well and can hit with then figure out how to carry it instead of picking a carry method then try to find a gun that'll work. JMHO, YMMV.
