There was an episode on Self Defense TV that dealt with "use what ya got" The instructor had an ancient single shot 20ga with a five shot holder around the stock. He would fire, pop out the old shell and insert the new one very fast. I'm sure with practice you could reload in the time it took the bad guy to come up from his flinch/duck position if you missed and had to take another shot In a self defense situation, if you need to fire 9 shots in 2 seconds to survive, you probably are in a load of trouble anyway.
