The North American Arms Mini-Revolver Convertible is a single-action 5-shot revolver with a 1.625-inch barrel. It ships with two cylinders — one for .22 LR and one for .22 Magnum — and the stainless steel frame keeps the overall package very light. This is a pocket-sized revolver designed for deep concealment rather than primary defensive use.

Detailed Features 

• Convertible Cylinder: Two cylinders included — one for .22 LR, one for .22 Magnum. Swap between them based on availability or preference. 
   
• Single-Action Only: Hammer must be cocked for each shot. Deliberate and slow to fire, which matches its role as a last-resort backup or outdoor companion. 
   
• Half-Notch Safety Cylinder: Resting the hammer in the half-notch between chambers prevents accidental discharge from a dropped gun. 
   
• Stainless Steel Construction: Corrosion resistant. The finish holds up to pocket carry conditions. 
   
• Wood Grips: Traditional look; small enough to not interfere with pocket carry. 
   

Target Audience 

 
Shooters who want a last-resort backup pistol or a deep-concealment carry option. Also popular for outdoor use where a small .22 Magnum can handle snake or pest control. Not suited as a primary defensive firearm. 
 

Usage Scenarios 

1. Deep Concealment Carry: Fits in a pocket without printing. 
2. Outdoor Use: A .22 Magnum load in 1.625 inches of barrel handles small pest and snake control scenarios. 
3. Backup Firearm: Functions as a last-resort gun when primary options aren't available.

NAA Mini-Revolver owners tend to buy knowing exactly what they're getting: a very small, very light .22 caliber single-action revolver. Discussions reflect that most buyers are satisfied within those expectations.

The convertible cylinder is frequently cited as a reason to choose this model over fixed-cylinder NAA revolvers. Running .22 Magnum for more punch or .22 LR for cheaper practice is practical and owners appreciate the flexibility. Build quality gets consistent positive marks -- the stainless construction is solid for something this small.

The grip size is the main practical criticism. Smaller hands handle it fine; larger hands struggle with control and the trigger manipulation required for single-action cocking. The 5-round capacity and short barrel accuracy limits come up often, but most owners accept this as inherent to the format rather than a flaw in this particular product.

Accuracy at distance is limited by the 1.625-inch barrel and fixed sights. Most owners report it's reliable within a few yards and treat it as a contact-distance or very-close-range tool.

The primary debate in community discussions is about role: whether a .22 Mini-Revolver makes sense as a backup at all. Those who carry it as a last-resort backup are generally comfortable with its limitations; those expecting primary-firearm performance are disappointed.
