ive got a friend with a .410 shotgun, it breaks down into 2 pieces, but is a single shot. he told me it originally was $400 but that was because they had to have it registered.. as i recall registration is free, then he told me it was in cali so... from what hes told me, he thinks its: a remington, single shot, breaks down, and is a .410 ... any ideas on what this could be? hes trying to send pictures but he takes too long so. give it a guess G&G'rs
