I would think about the 19. It is also 9mm like your 26, the mags will fit your 26 as well. This way you will have to only buy one Cal of ammo, 9mm is the least expensive. Although the 23 is a very sweet one too! You can also get the 9mm barrel which will give you the option of 9mm or. 40 out of the same gun. Just something to think about! Glad to hear your hooked on GLOCK!
