The Standard Manufacturing DP-12 in 12 gauge (brand part no. DP12W1) is a manually cycled, double-barrel pump-action shotgun machined from aircraft-grade 7075 aluminum, listed here despite being pump-action rather than semi-automatic. Standard Manufacturing builds the DP-12 with dual side-by-side barrels fed from twin magazine tubes, delivering two shots per trigger pull for a total capacity of 16 rounds including the chambers. Among semi-auto shotguns in the semi-auto shotguns category, the DP-12 favors shooters who want maximum firepower and accessory versatility from a purpose-built defensive platform, and this Works Package #1 configuration adds a factory-installed optic and accessory kit.
