Micro-revolvers have a clear role for close-quarters defense and discreet carry: they must be reliable, easy to draw, and deliver meaningful ballistics from a very small package. For users who want a compact defensive tool that doesn’t compromise on materials or sighting, this platform answers the need.

NORTH AMERICAN ARMS SENTINEL is a pocket-sized revolver purpose-built for tactical carry. At just 4.9″ long x 2.8″ tall with a 1.425″ barrel, the SENTINEL uses 17-4 stainless steel construction for toughness in daily carry. It features a 5-shot cylinder chambered in .22 WMR, accessible cylinder pin and a swing-out cylinder for faster, more convenient reloads compared to fixed-pin micro revolvers. Shop this product

Compact design and materials

The 17-4 stainless steel frame on the NORTH AMERICAN ARMS SENTINEL delivers corrosion resistance and solid lock-up in a tiny footprint. Textured rubber grips improve purchase under stress and mitigate felt recoil from .22 WMR rounds. Design cues that echo the PUG and Sidewinder profiles make the SENTINEL familiar to fans of micro revolvers while adding modern ergonomics.

Performance and caliber

Why .22 WMR?

.22 WMR (Winchester Magnum Rimfire) offers substantially more energy than .22 LR in the same small platform, improving terminal performance and barrier penetration at close range. In a five-shot cylinder, the cartridge balances manageable recoil, compact ammo size, and increased stopping potential for last-resort defensive scenarios. The SENTINEL’s barrel and sight package are tuned for short-range accuracy.

Sighting and reloading

Equipped with XS sights and the option of dot-style or Tritium front sights, the NORTH AMERICAN ARMS SENTINEL gives fast target acquisition in daylight or low-light conditions. The accessible cylinder pin and swing-out cylinder let you reload more quickly than traditional pin-frame micros—an important tactical advantage when time matters. View product details and pricing

Carry considerations and pricing

With its 4.9″ overall length and slim profile, the NORTH AMERICAN ARMS SENTINEL is built to live in a pocket or small holster without printing excessively. For buyers seeking a high-quality micro-revolver, the SENTINEL is priced at $404.99—competitive for a 17-4 stainless build with premium sights and grip options.

For tactical-minded shooters who prioritize concealment, durability, and a step up in performance over .22 LR, the NORTH AMERICAN ARMS SENTINEL is a purpose-built option. Check current availability
