I carry a soft briefcase from guntotenmamas.com
In it is my CZ-75B and a spare magazine,,,
A few personal items like aspirin, spare glasses, and such stuff,,,
I also carry a few food items like energy bars and one small bottle of water.
I have one of those tiny first aid kits with band-aids and other such items,,,
Perhaps the most often used item is the needle and tweezers,,,
Splinters abound where I work.
We jokingly call the bag a "murse" or man purse,,,
And like a woman's purse it fills up with junk rather quickly.
But I find it very handy,,,
A holdover from my student days I guess,,,
For those 8 years I carried my life in a messenger bag.
