Is there some kind of legal problem with street-sweeper shotguns? Bc i nvr see any for sale, and if theyre not legal unless theyre grandfathered, is it that stupid crap the government made up about them not having "sporting purpose" . I think a street sweeper, SPAS12 and SPAS15 would b great for 3 gun, from the kind of guns i see on the commercials for 3 gun shows.
