I tried to conceal my g19 today with a t shirt. Was not happening, had to switch to a single stack.
Mine conceals great at about 1 o'clock with a proper holster under a not even that loose t-shirt. I do this almost daily.
As for the OP, I keep asking myself the same question, but in a different context. I keep wanting to get a Glock 17 for... reasons. I keep telling myself that the 19 is everything I need in a 9mm Glock (fullish size) AND I know I shoot it about the same as the 17.
Yet I still want that 17.
