Tristar shotgun for HD

I'm looking into getting a tristar shotgun for home defence but want to know if anyone out there has any experience with them and weather it is good or bad experience. Also which would y'all suggest I get if either, SA or pump? I like the idea of the sa because you don't have to physically reload after each shot it does the work for you, but it has also been brought to my attention in the past that you have a greater chance of malfunction with the SA's and it takes more to effort clear those malfunctions than with the pump any and all suggestons and advice aprieciated thanks.
