Description

The Iver Johnson IJ-1000 .410ga is a single-shot, break-open shotgun chambered in .410 gauge, designed for simple, lightweight use such as small game hunting or recreational shooting. It features a traditional break-action with a manually cocked hammer and a blade front sight, typically with a folding stock for compact transport and storage. These shotguns are straightforward in design, often including interchangeable or fixed choke options and accepting standard .410 shotshells up to 3″ in length.

Notes

• .410 Bore Characteristics: Light recoil and modest shot payload make .410 ideal for small game and beginner shooters, though effective range and pattern density are limited compared to larger gauges.
• Model Variants: Iver Johnson marketed several .410 single-shot variants (e.g., IJ700 series) with similar specs — the IJ-1000 likely fits this pattern if it’s a naming variant or updated designation.
