Monolith Arms P-12: The P-90-like Shotgun That Never Was
Back in 2007/08 a company called Monolith Arms was promoting a pump-action 12 gauge shotgun they designed. The shotgun was notable because it fed from a horizontally mounted magazine inspired by the FN P90. They shotgun was promised to be on sale in 2007, when they did not ship it in 2007 they promised it in 2008, but again it never materialized.
Maybe Monolith Arms were just a little to early to the market. There is a lot of interest in high-capacity shotguns these days, for example the Kel-Tec KSG, and a number of high-capacity solutions for regular shotguns such as the MD-20 drum magazine for the Saiga-12. It would sell well today.
Many thanks to Jacob for the photos.

they need to make a 50 caliber semi rimmed 3&1/2" with compatible case dimensions to the 500 S&W, then they cant be banned because they are technically DDs like all other shotgun shells even the 28 gauge is still subject to random bans by the BATFE by simply saying they dont have a sporting use. then we can make a semi auto(piston driven)+pump rifle/shotgun(with a rifle'd and smooth bore barrel that works with the 50 caliber shotgun shells 500 S&W magnum, and 500 S&W maximum, same dimensions as the 3&1/2 inch shot shell, in a design somewhat like the P12 imagine 25 rounds of 500 S&W magnum, maximum or 50cal double brass with triple ought buck, and to asociate the 500 shotgun shell with shotguns it will be called the 510 actual projectile diameter being .5 or less
you could just make a 12 ga shell with a rebated rim to 20 ga in fact remington had over run of 20 ga that they convert to be 12 ga or was it the other way around..
