I have all the Glock 9mm models from the 26 to the 34. For concealed carry the 26 with a 2 round pinkie extension is great. For general all around the 17 is still the best all around.
Just picked up a 26 last week and would have to say it's now my favorite. Oddly enough I can shoot it better than my 19 but that is probable an issue with the operator and not the hardware.
