At 7.05ish you can see the officer retrieve the shotgun and starts shooting at 8.41, but since he didn't have any extra ammo for it, it ran empty VERY quickly and was then of course useless. I have to wonder that if he'd be able to keep shooting, the female officer might not have been wounded?
A sidesaddle, buttcuff or belt mounted shell caddy might have helped, {assuming he was authorized to carry extra shotgun ammo to begin with} but IMO nothing beats a shoulder bag for quickly grabbing a bunch of shotgun ammo.
Just throw the strap over your head and you've got 50 or more loose rounds ready to go.
I rock one of these 3 cell bags but even something like a dump pouch will work.
