What's Included
- Hopkins & Allen Hammer Double Gun (12 Gauge)
This side-by-side retains the hallmark Hopkins & Allen setup: external hammers with sideplate locks, double triggers, and a top-lever break action. There is no tang safety; instead, the gun uses half-cock notches. The single brass front bead sits on a solid, matted top rib for a clean sight picture.
The barrels measure 20 inches and are configured CYL/CYL, providing true Cylinder bores in both tubes. Chambering is 2 3/4 inches, as specified. The bores appear smooth in the provided photos with no visible twist pattern, aligning with the CYL bore configuration.
Furniture includes a splinter forend with hand checkering and screw retention, plus a pistol-grip buttstock with a checkered wrist. A ventilated recoil pad has been installed as a customization, yielding a 14 inch length of pull.
Additional details include a barrel-mounted swivel stud on the bottom rib near the muzzle. The receiver marking reads "Hopkins & Allen Arms Company / Norwich, Conn. U.S.A.," placing this example in the Arms Company era, a point of interest for collectors seeking period-correct features.
Overall, the configuration is straightforward and practical: 12 gauge, 20 inch barrels, 2 3/4 inch chambering, CYL bores, external hammers, and double triggers—delivering a classic SxS layout with a period-correct look and feel.
