Homemade Slam-Fire Shotgun with Detachable Magazine

I have seen several YouTube videos of simple homemade slam-fire shotguns made from water pipe bought from a hardware store. All of them were single shots and somewhat difficult to reload. I decided to try to build a slam-fire shotgun with a detachable magazine that would make reloading a shell much faster. With each problem I came across I had to engineer a solution. Finally I was successful. If you go to my website you can view a video that shows how my slam-fire works in greater detail. You can also download plans in case you want to make your own homemade shotgun.
