Description

The NAA Mini-Master 22 LR Revolver is the largest and most shootable of North American Arms’ mini revolvers, and the one that behaves most like a real handgun. It carries five rounds of .22 Long Rifle in a bull cylinder, wears a 4-inch heavy vented barrel, and adds adjustable target sights and an oversized rubber grip to a design that is otherwise famously tiny.
A Mini Revolver You Can Actually Shoot
Most NAA mini revolvers are built purely for concealment, with a barrel measured in single inches and a grip you hold with two fingers. The Mini-Master is the exception. The 4-inch barrel gives a real sight radius, the bull cylinder and heavy vent barrel add stabilising weight up front, and the oversized rubber grip fills enough of the hand to shoot deliberately rather than just point and hope.
NAA Mini-Master 22 LR Revolver Sights and Barrel
This version comes with adjustable target sights, which is what separates it from the fixed-sight models and what makes it worth taking to a range. The barrel is stainless with a ventilated rib, machined heavy rather than slim, and the whole revolver, frame and cylinder included, is stainless steel. There is nothing on it to rust and nothing that needs babying.
Single Action, Five Rounds
The action is single action only: cock the exposed hammer for each shot. It is deliberate by design, and combined with the safety notches machined between the chambers it means the revolver can be carried fully loaded with the hammer resting safely between rounds rather than on a live one. Loading is done by removing the cylinder pin and the cylinder, in the traditional mini revolver fashion.
Safe Storage
Store handguns unloaded in a locked safe, lockbox or with a cable lock, and keep ammunition separate when children are in the home. Quick access safes let you keep a defensive handgun secure but available. Teach everyone in the household basic firearm safety rules.

Made in the United States
North American Arms has been building mini revolvers in Provo, Utah since the 1970s, and the machining quality is a large part of why these hold their value. Everything is stainless, the fit between cylinder and frame is tight, and the company still services guns it made decades ago. For something this small, the build standard is considerably higher than the size suggests.
Why Buyers Choose the NAA Mini-Master 22 LR Revolver
Mini revolvers usually force a choice between pocketability and being able to hit anything. The Mini-Master takes the second option seriously without giving up much of the first: at under eleven ounces and less than eight inches long it still disappears in a jacket pocket or a glove box, but with target sights and a real barrel it is a gun you can practise with rather than one you simply carry and hope about.
Who Should Buy It
This suits the shooter who wants a genuinely small stainless revolver that is still enjoyable at the range, the outdoorsman looking for a light kit gun for a pack or tackle box, and collectors of North American Arms revolvers who want the most capable model in the line. Note that it is single action only and loads by removing the cylinder, so practise the routine before you rely on it, and use a pocket holster to keep the hammer covered.
