I have a glock 42 that I am qualified with to carry as a BUG but I am considering getting a glock 43 and my duty weapon is a glock 19. How would you guys recommend carrying it on body and in what holster? And what brand of go bag should I use and what should I in it for patrol? Or would I be better off going getting something like the First On by First Spear? For a active shooter grab and go kind of rig. I am open to new suggestions.
