Dr 2 B - I didn't mean to blast him, but it's true. It is easier to just leave your shirt untucked!
I am about 5'5" and 135, almost the same exact size as the OP, and unless they come out with some smaller guns, pocket carry just isn't an option.
It probably never crosses an average sized persons mind (why would it?), but if your pants are of a significantly smaller size so are your pockets!
I wish I could pocket carry, but have found that in IWB or a good high ride pancake holster are best for my build. With that you either wear a cover garment or untuck your shirt.
Or maybe someone will start manufacturing extra small mouse guns designed for midget pocket carry!
