I ain't gonna lie to ya, the Glock 26/27 series is a pocket full of gun. If you are on the slim side, it's gonna show. However, I do know of one other member here who's kinda slim who also pocket carries a G27 with no issues. Maybe he'll chime in and give you his take on it as well. It took me about a solid two weeks before it didn't drive me absolutely nuts. But it's like anything else...you overcome and adapt.
