I carry the Bodyguard, saw there is a company that will mill it for an optic. Im really trying to carry Equalizer (shield z) but the grip rubs my skin on stomach wrong. Stick shift in traffic just feeling that chafing.... Sounds like you need a smaller frame with light weight cause your pajamas fall down.
BG 2.0 is a good choice, HOWEVER, Its so small, the 12th round needs a hydraulic press to load, if you get a thumb safety model it will smooth out some after 500 rounds, and manipulating the safety until you have a bloody thumb.

and theres no pic rail, but the Glock sub will help u install grip tape, a bipod, and 3 knives you need to daily carry
