S&W model 1000M in 12 gauge 3" chamber with a 30" full choke. Bore is smooth and clean. These are for 3-in magnum loads. They will not cycle anything less. The bluing and the wood are really an amazing condition overall. However, there is a gouge in the wood forend. Happy to send multiple other pix.
