Normally. I would prefer a 1911 single stack; but, for concealed carry, I want something I don't have to worry about - I had a Glock 26 for 8 years. I really didn't like it at the range, but it was a gun I could carry all year long. And, even in the hot summer, I could put it back on the shelf and not have to worry about it rusting. I don't want something I have to wipe down with oil every day or even every week.
Last year I found out that the Walther P99s also have a tennifer coating, so I sold the G26 and got a Walther. The full size is actually 1 of my fav guns, but I really like the compact.
So, I carry the compact - It is 10+1, and I rarely ever bother to carry an extra mag.
