When I'm not at work I carry my wallet, keys, small pocket knife, and a para ordnance P-12 .45 acp in a IWB holster. If I'm leaving town I also carry two spare mags in a belt pouch.
I can't carry at work, my company has the ignorant policy that "no firearms are allowed on company property, even in your personal vehicle, if you are caught with a firearm you will be fired"
