Who said full size? And since the premise is of a one gun for all situations, I don’t think a pistol is good for anything past 50yds and I certainly wouldn’t want to be hunting with a 9mm. Just a personal preference but concealability is not in my top 5 priorities for my one and only weapon.Glock 19X. I don't know how some of you are concealing shotguns and full-sized ARs.
