ive never had to fight with my shotgun but i can imagine how hot it gets after multiple rounds are fired. I have a sawed off 12 i bought from a police auction that was an entry weapon and it came with one on it. Really there arent a lot of places to grab the gun (its got a pistol front grip) so in an emergancy situation where you are shooting and then need to grab your gun and backpedal i could see it saving you burnt hand you might need later.
"i got the most powerful gun in the world........an .88 magnum. It shoots thru schools......"
