1911 commander with a 8+1, 2 more 10 rounders in a custom back pocket wallet/mag holder... occasionally a BUG< usually on rent collection days. My brief case usually has 4 loaded mags for 1911, and that goes most of where I go. WHy? because I can.
Just to pull a buddy's leg who carries just a J frame, I showed up at his work carrying my usual load and a Galco shoulder holster with a G27 and 2 G18 33 rounds hanging from the mag pounches, yeah I made some extension snaps to hold them in, but it was more a gag.
