I started with the G19 and love it but regularly reach for the G26. Best holster I have found for shorts and T shirt carry for the Glock is the smartcarry (I live in Houston so it is hot here!) however the easiest and most comfortable option I have found for shorts and and t shirt wear is a S&W J frame in a PCS pocket holster . Mine is in Airweight in .32 H&R so I have 6 shots. If I am wearing cargo shorts I will put the G26 in a Nemesis holster in my cargo pocket balanced by mags, cell phone, keys etc in the other cargo pocket but that's not easy or convenient.
