Hit the thrift store and buy an old leather purse with a long strap. Cut all the internal guts out. Open a wire coat hanger and have the shoe repair shop sew it into the top rim to keep the mouth open.
Sling the purse over her shoulder, around her neck, fill it with magazines / ammo and go to it.
These are also called "possibles bags" by some shooters.
Armed and Safe: Not just a theory
If it time to bury them, it is time to dig them up.
Remember, "Behind every blade of grass."
