I owe two 1911's (a Kimber in .45 and a Springfield Armory in 9mm). Both of these are fine handguns. I also own a Glock 23 of which I am quite fond. As for carrying purposes, I would, and do, pick up the Glock 23 every time over either of my 1911 for several reasons.
Weight. The 23 weighs quite a bit less than either of my 1911's. This serves me well with my carry holster since it can be smaller and rides nicer on my belt and side.
Size. I like the size of the 23. While I mostly carry my Glock 27, I do carry my 23 or my 19 at times. I have others in my carry stable such as some Kahr's which are fine carry pieces.
Capacity. Hard to beat a double stacked magazine holding some extra bad boys if needed.
Reliability. I would bet the Glock has a much higher percentage of reliability than most any 1911.
Simplicity. I am not a fan of carrying Condition 1 and with a 1911, that is the condition one should carry that type of gun in if it is to be ready at an instant's notice. With the Glock, it is even simplier than a single action in Condition 1. No external safety, so all you do is point and pull the trigger.
Am I a big fan of the Glock and therefore have blinders on when considering other weapons for personal defense? Absolutely not! I admire anything that works as it was designed and works well everytime. Ten years ago, I bought two Glocks (a 23 and a 27) and soon after got rid of both of them because I didn't like them. In the past 15 months, I've bought 4 Glocks (23, 26, 27, 19) and I like all of them. They will remain in my collection. Go fiigure.
So if you are looking for a gun to take to the range and punch holes in paper, the 1911 is the better choice. If you are looking for a gun to serve multiple purposes, the most important of which is personal protection, get the Glock.
And consider the 23 along with the 22.. you might be surprised.
