I carry in my front pocket wearing a Break Away pair of shorts. I can hide my Glock 40 in that pocket that is sewed into the shape of a holster. I also use a big Sticky Pocket holster to smooth out any defining lines when I sit down. The Break Aways have two snaps along the top of both front pockets (Ambidextrous carry) that unsnap and leave you with direct access to the gun. It's faster than trying to sling a shirt out of the way to get to either an OWB carry or a IWB carry. I normally carry my 1911 in the Break Aways because it is an 1" shorter which does make a difference.
