Has anyone here ever owned/seen/played with or otherwise dabbled with one? I am working on purchasing an 1100 for a remote-line CO2 swap and a SPAS-12 conversion. And I was just wondering if anyone else had ever even used on. I know thier downside in most peoples opinions are that they are shell eject, or even that they cant hadle green gas, but I think the concept is pretty sweet, seeing as each shell can be loaded to different specs to create different effects such as birdshot/buckshot/slugs from what i have seen done with them
