Hello, this my first post on the forums but I've been browsing on my android phone for awhile. I currently own 2 glock 19s, and a glock 23. I'm in the market to purchase a subcompact and a fullsize within a years time in either 9mm, or .40 s&w. I'm having difficulty deciding on the models although after browsing i'm convinced the glock 26 would suffice as the subcompact. That leaves either the glock 17, 22, 34, 35. Please give me some advise, it will be used as a recreational and duty firearm. Things to consider; I do use my firearms for employment, i'm an armed guard and NRA pistol instructor (although the instructors license isn't utilized as much as I'd like) I live in CA so I can only own generations 1, 2 & 3, with 10 round mags. I'm only licensed with 9mm and .40; although 357 sig interests me I'd like to keep recommendations to 9 & .40. I normally use a OWB serpa for ccw, and serpa level 3 for duty. I have 8 g19 mags and 3 g23 which is why i'm leaning towards a g26 over its .40 counterpart. Similarly why I've been thinking about a g22 or g35. still the critical failures reported with glocks chambered in .40 s&w have given me cold feet about purchasing another even though my glock 23 works like a charm.
