The mag fed 12 ga shotgun, I am pretty sure is a South African invention. As a result of all the sanctions against SA, they were forced to come up with their own weapons cause they couldn't import any. Some were good some were bad. I remember seeing one in G&A quite some years ago. The shotgun has a pistol grip and the mag feeds through this grip. Even with the shorter shell, it is a chore to get a good grip on it even with larger hands.
