For the MOST part, a 1911 (usually my Springfield customized, at least recently) in a Galco Summer Comfort with 1 extra magazine (Both CMC PowerMags) and Hornady 185gr XTP +P rounds.
I've carried my new Glock 20 in the same holster (well a different holster with the same name) with no extra magazine (if I need to fire more than 16 rounds I'm probably screwed). I'm not accustomed to the Glock yet, but it will probably work it's way into rotation more often as I get used to it.
