Rock Island sells the Meriva 3-in-1 Combo as a 12 gauge pump with two barrels, a smoothbore cylinder tube and a vent rib tube, with the listed barrel length at 25 inches. The receiver is aluminum in a marine chrome finish, the furniture is synthetic with a ribbed forend, and the stock is removable, with a pistol grip offered as an alternative. Capacity is 4+1 with 3-inch chambers, weight 6.17 pounds, overall length 39 inches as configured. Sling swivels, a bead sight and a manual safety are fitted, and multiple chokes are supplied.
Three configurations are the point: vent rib barrel and stock for sporting use, cylinder barrel and stock for the home, cylinder barrel and pistol grip for the shortest package. The marine chrome receiver resists corrosion. In Connecticut the vent rib setup also covers deer, since a 12 gauge with single projectiles is allowed on private land from November 18 to December 8 and on state land in that season, which takes shotguns and muzzleloaders only.
