Well, did you perform a barrel check regularly on your Glock? If you do, it would be A-OK, but for a novice shooter, they don't generally maintain their firearms (Especially folks that does not clean their barrel after use), which means they will have a nasty surprise sometime down the road. I own and shoot a Glock in Australia, too, since they are the cheapest and easiest to get here.
1911 for me is hit or miss. If you really love a firearm, that's the go-to gun you get, but I was once left with a choice: I could either go for a 1911 or a Colt Python, I went with the Python. Had not regretted it ever since, for me, the only firearm that beats a Python is a Colt SAA
When you are talking about CC, it's ALWAYS down to which firearms you are most comfortable with, if I am doing CC, I would probably carry a Glock, it's light weight, ergonomic, it's extremely well-suited for CAR, and as I said, I had never shoot a P220/P226/P320, so I have no reference point.
