What did you go with for a bag? If it has a 2" sling, and the sling is about two feet long, something I spotted that you might want to look at as an EDC+ carrier that you can leave in your office.

High Speed Gear's waist pack. It has a pair of pouches, each about the size of three stacked m16 magazines (guestimating it at about 7.5 long, 3" wide, 2.5 deep), one square one, and a long tunnel pouch for ropes and the like. It fits onto a 2" wide belt; everthing closes with flaps and fastex buckles except for the zippered square pouch.

bunch of folks have it for the same price (give or take a few cents), but tirad has the best picture. http://www.triadtactical.com/store/item/ujwr/High_Speed_Gear/HSGI_Sniper_Waist_Pack.html
