Toying with the idea of picking up a baby glock but am having a hard time deciding on the caliber as well as whether to try a gen 4 or try to hunt down a gen 3. Currently I only have two glocks in my collection- my beloved g17gen3 and a 21sf that is also gen3 and I would never consider parting with them. I also own a few pocket pistols- LC9 and a Kahr PM40 so shooting a small gun is nothing new to me so out of the three... 26,27, & 33 which would u recommend? I already own 2 9mm and 2 40s so that knocks the ammo ? out and although I do not have a .357sig... I still want one despite the ammo cost. I do not plan to carry this gun often or even at all... it will most likely become a glove box gun so I guess it comes down to which caliber would u recommend and are the gen4 issues still an issue or has that been resolved??? Any input would be greatly appreciated.
