First off, I am absolutely in love with my new Gen 4 17. It is my second glock. My first was a Gen 4 23 that I loved, but I eliminated 40 caliber from my pistols. Dwindled them down to 9 and 45. So right now I only have 3 pistols. A full size Ruger 1911, A Springfield XDS that I carry, and my 17. I have an abundance of 9mm right now, but not much 45. I'm thinking of adding a 26 to my arsenal because of my ammo situation plus it Would give me another carry option. It only seems natural, right? Or should I get a full size and go with a 21? I'm eyeballing a fde Gen 4 26 to go with my 17. It just seems like they'd be a happy pair!
