Throwing the G26 out there since it hits your "actually like shooting" criteria pretty well. Yeah it's G19 width (my preference) so it's not the easiest carry. I don't disagree w/
@Gravel but that width and weight is exactly what makes it shoot like a chopped G19 instead of a snappy micro. If the whole point of replacing the BG is that you want to train w/ what you carry the G26 rewards that more than a thinner gun will IMHO.
Two things:
1. Get the
Gen5 MOS if you can find one. Factory optic cut means no milling and MOS holds resale way better than a one-off RMR cut w/ coating costs ($200+) that locks the next buyer into your footprint choice.
2.
Mag commonality is awesome your reload can be a freedom week G17 17-rounder.
Not the pick if deep concealment in a t-shirt is the priority. ShieldX, BG and 43x wins there but I don't enjoy shooting those. Also not a fan of the Glock 48.
