Some contradictions in the OP - both of those Glocks are hi-cap double stacks and neither would be much fun to conceal daily.
I figure a ccw is a self
defense weapon, 6+1, plus a spare is hopefully enough.
I'm a big fan of .40, but I see it as a better option to 9mm, not better than 45.
I've found one pistol that I think does it all really well... the Glock 27
Its not perfect at anything - its not a tiny ccw and its not 13+1 of 45ACP either - but 9+1 of .40 is a bunch of firepower in a small concealable very shootable package, making it suitable for almost any type of defensive use.
For a .45 for carry you might really like the Glock 36 plus a spare mag on the opposite hip.
For general use and home defense you might like the Glock 30.
