I’ve set up a pair of XL uppers with Macro lowers and spent entirely too much money for the amount of mags I obtained. As above, I do not view these as a double stack 9 killer — they recoil more harshly and recover slower. This pistol is, however, what I wanted my G43X to be. The 43X/48 frame doesn’t work with my hand (my natural grip depresses the mag release) and I didn’t agree with the triggers. This pistol is similarly flat, similarly sized, similarly light — with a better trigger and an optic.
