ACME North has a used but excellent Harrington and Richardson Pardner Model pump action shotgun in 12 gauge.

this riot gun style 12 gauge pump shotgun has an 18 inch barrel with the site. There is little evidence where to the metal or the black polymer synthetic furniture and it comes equipped with an elastic five shell holder on the butt stock. The shotgun also comes with front and rear attachment points for quick disconnect sling swivels. The shotgun would be an excellent choice for home defense applications.
