North American Arms Mini-Master .22 Magnum Single Action Revolver 4″ Barrel

The North American Arms Mini-Master is the full-featured evolution of NAA’s legendary pocket revolvers, chambered in .22 Magnum for meaningful terminal performance from a compact platform. Built on a stainless steel frame with a 4-inch barrel, it delivers a longer sight radius and improved velocity compared to NAA’s shorter-barreled models. With adjustable sights and single-action operation, this revolver is designed for the shooter who demands precision and reliability from a small-format revolver. It’s equally at home as a capable trail gun, reliable backup piece, or dedicated small-game firearm.
