North American Arms Mini-Master | 4″ Vent Rib | 5rd | NAA-MMC

The North American Arms Mini-Master is a compact single-action mini-revolver built around NAA’s Magnum-frame design and intended for precision-oriented pocket revolver use. It features a 4-inch vented barrel, fixed Marble Arms sights, and a five-shot stainless cylinder. Configurations are commonly supplied with a stainless finish and a black finger-grooved rubber grip.

This compact revolver is suited to precision target shooting and recreational plinking, and is often chosen by shooters who value a small, mechanically simple revolver for range use and small-game fieldwork.
