Hello neighbor. I waited until the Gen3 Glock to jump aboard. The baby Glocks are nice. I have a Glock 27 which I convert to 9mm with a Lone Wolf conversion barrel and some 9mm mags. It make for cheaper range time and gives me flexibility. I carry it with the stock 40 S&W setup.
I really like how easy it is to maintain and clean a Glock.
So far, I have 3 Glocks and they are all great (19, 20 and 27).
I make sure to keep plenty of ammo and magazines. In anticipation of shortages, I also have magazines for other Glocks I have not bought yet.
If you get the Glock 26, the Glock 17, 18 and 19 magazines will function in it too.
