Iver Johnson Hammerless Hercules Grade 16 Gauge Side-by-Side Shotgun – 28 in. Barrels, Pre-WWII American Double
This Iver Johnson Hammerless Hercules Grade offers a classic pre-WWII American double built on the 1915 Reising mono-bloc patent. Known for its robust construction and affordable price when new, the Hercules Grade earned a following among upland hunters who appreciated its durability in the field. Matching serial numbers on the receiver, barrels, and fore-end confirm originality, while the owl-logo hard-rubber butt-plate and hand-cut diamond checkering add authentic Iver Johnson character.

What’s Included
- Iver Johnson Hammerless Hercules Grade 16 Gauge side-by-side shotgun
The 28-inch blued steel barrels are chambered for 2 ¾ inch shells and use an extractor system, simplifying reloads without the added complexity of ejectors.
A case-hardened receiver pairs with the blued barrels, displaying the period-correct finish combination typical of Hercules Grade guns. The automatic tang safety and double triggers provide familiar controls for traditional shooters.
The walnut stock features a 14-inch length of pull, a semi-pistol grip, and crisp hand-cut diamond checkering that still offers positive purchase despite field wear. The matching splinter forend completes the classic upland profile.
Assembled in the USA during the 1913–1941 production run, this full-size 16 Gauge remains a representative example of Iver Johnson’s mid-grade doubles that balanced affordability with reliability for everyday hunters.
