I currently have a Kahr PM9, SA-XDM 3.8 9mm Compact. Thinking about adding a Glock to my collection (finally), but I'm torn between a 26 or a 27. I like the idea of having a 40 cal since both my other pistols are 9mm, but I don't like to idea of spending the extra money for the ammo. If I do the 27, I would probably do a Lone Wolf to make it a 9mm. What do you guys think?
