To expand on this, if you get the glock factory 10 round mags for the 27, you have the same capacity as the 26, and with the fingertip extension which is very helpful with the sub compacts. Its all personal preference to you, I like the .40 and plan on sticking with it. The recoil in the 27 to me isnt to bad and if you train with it, you shouldnt have an issue making a follow up shotIn my opinion I tend to go with the additional capacity and less recoil in a smaller packaged gun like a sub compact. I feel I can get faster followup shots and can carry more in the one magazine that I have in the gun when I am out and about.
Since you already have a G22 I say go for the 27 so you can share mags and stock up on one caliber. I have a G23 and G27 and love them both. Looking to get a G22 myself soon to complete the family.
I currently have a Glock 22 and I'm looking for another Glock to add to the collection. I want one that is either to conceal but I don't know if I should go with another .40 or a 9mm. What do you think...Glock 26 or 27
