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

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.
