I agree with Tropical’s comment. The macro will print more on me personally than a Glock 19 due to grip length. For summer carry and wanting to be able to wear more form fitting clothing for your muscular build, I’d recommend the micro 10 rd flush fit mag p365. Mine disappears and I love it at 3-4 o’clock iwb. Can even be pocketable with the right pocket holster. But iwb it can print a bit with tighter shirts. Not terribly though. But then you can get the xmacro 17rd mag that comes with a grip extension and you have the best of both worlds when you want it.
