I've had a Maxpedition Versa since the company started making them. I really like that tough little shoulder bag, but I haven't carried in it since the first day.
It took about zero minutes to realize everyone saw it, looked at it, admired it, hated it, but most importantly.... NOTICED IT.
I don't want people looking at my concealed carry weapon, and I really don't want it in a bag that might be snatched.
Meanwhile, it makes a great bag for travel, or a ready bag in the house. For a carry weapon? Nope, not for me.
