Check out Midway's range bag on sale for $30.00 Just got mine yesterday and was hard pressed to use all the available space!! Shoulder strap, two bags in one, 2 pistol cases, water bottle holder, brass bag,6 outside pockets with bidirectional zippers,at least 12 mag loops. Worth checking out. And if you don't like it for the range, you've got a great weekender bag for traveling.
When in trouble, when in doubt, run in circles, scream and shout.
