Iver Johnson IJ1000 Features The Iver Johnson IJ1000 is built around a 5 shell revolving cylinder chambered for .410 with a 3 inch chamber giving shooters a unique repeating action in a compact shotgun platform. Its double action trigger with external hammer allows for both quick double action shots and more deliberate single action follow-up shots.

An aluminum forend with additional Picatinny rail space gives room for lights or other accessories to be added. The fixed black synthetic stock keeps the overall package lightweight at 5.15 pounds while a manual safety lock adds an extra layer of security.
