For a main CCW, would you go with a Glock 26, 27 or 30.?

BTW the 26 is a 9mm, 27 is a .40S&W, and the 30 is a .45 ACP. My G17 is a bit bulky for a CCW and I'm sold on a subcompact Glock for that purpose. By the way, I know that each person has his/her own fit and you should carry what you're comfortable with; however I am curious to know if anyone has advice given their personal experience with these Glocks (or at least the calibers).
