I came upon a model 1000 20 gauge autoloader in a pawn shop. It is marked "made for Smith & Wesson in Japan" Gas operated, 26" barrel, IC fixed choke, really good condition; obviously shot very little. It is lightweight and seems to fit me. Externally, it looks like a Remington 1100. Price is $335 OTD.

I am unfamiliar with this gun. What say you?
