I have owned, at one time or another, the G19, G20, G21, G24 and the G27. I'm now pretty much dedicated to the .45 so I would eventually like to own a G36 (maybe a G30 but it's kinda' "fat"). I would own those for CCW if I did finally get one. I like all kinds of guns (especially handguns) but I really like the Glock because it's so.....utilitarian, accurate, dependable, ugly, almost unbreakable, etc., etc. If I was going to own one in a 9 mm or 40 cal. it would be a G19 or G23. Just my $.02.
