Like many others it depends on what I'm wearing and where I'm going. Also I like to switch off on what I carry just because I can.

Most of the time I carry the bigger ones IWB because they conceal better. A 1911 is the biggest. I like my Springfield XDS because it's thin and medium size but still a .45acp. A S&W 2.5" .357 OWB or IWB. An LCR .38 and a Colt .380 pockerlite carry nicely in a front pocket. I've also got a 9mm Doubletap for times when two shots are better than none.
