If he’d needed a second shot, he was SOL. Of course, it probably jammed from being limp wristed firing from that awkward position.
Kel Tecs are OK, but hardly a first tier handgun.
The surprise was how many times the weapon was disabled by pieces from the animal - wouldn't go back into battery.
Moral of his research - if you're using an auto, don't stick the muzzle up against your target or you might not get a second shot (should you need it).
You're right on about Kel Tecs. They can certainly benefit from some stones and semichrome applied by skilled hands.
