The NAA Mini-Revolver in .22 WMR is one of the smallest production revolvers available. At 4.62 inches overall and 5.90 ounces, it fits in a shirt pocket or rides in a vest without adding meaningful bulk. The single-action mechanism and 1.13-inch barrel are best suited to close-range backup use or as a trail gun.

Features 

The stainless steel frame and cylinder resist corrosion well. The half-moon front sight is minimal but workable at the short distances this revolver is intended for. .22 WMR from a 1.13-inch barrel loses substantial velocity compared to a longer barrel, which is a genuine limitation worth understanding before purchase. The SAO design means each shot requires manually cocking the hammer, which acts as a natural safety measure.

Most owners are clear-eyed about what the .22 WMR Mini-Revolver is: a backup or trail gun, not a primary defense weapon. That framing shapes most of the positive feedback, where people appreciate its near-zero carry weight and the reliability of a simple revolver mechanism.

The five-round capacity and limited stopping power at .22 WMR velocity from a 1.13-inch barrel come up regularly in critical discussions. Recoil is described as snappy for the caliber due to the light frame. Long-range accuracy expectations are not realistic at this barrel length, and most honest reviews acknowledge that.

Trigger pull varies in user reports from manageable to stiff. Build quality is generally praised. The revolver's niche as a concealment or collection piece is well understood by those who buy it.
