About this product
The NAA Sheriff 22 WMR 2.5 in Stainless 5-Rd is a single-action mini-revolver chambered in .22 Winchester Magnum, built on a compact 1860-style frame. This stainless-steel revolver weighs 5.6 ounces and features a 2.5-inch octagonal barrel with a five-round removable cylinder. Its mechanical simplicity and corrosion-resistant construction make it a distinctive option for discreet carry and recreational shooting where historical styling is valued.
What is the NAA Sheriff used for?
The NAA Sheriff serves primarily as a deep-concealment backup pistol or minimalist trail gun where every ounce matters. With an overall length of just 5.75 inches, it fits in a boot holster or pocket organizer without printing. The .22 WMR cartridge provides adequate penetration for close-range defense against small predators, though I'd never recommend it as a primary defensive weapon.
How does the NAA Sheriff compare to the Ruger LCP II?
The NAA Sheriff offers superior concealability but significantly less practical firepower than the Ruger LCP II. While the Sheriff's 5.6-ounce weight is 40% lighter than the LCP II's 10.6 ounces, the Ruger carries 6+1 rounds of .380 ACP with a double-action trigger and faster reload capability. For serious defensive use, the LCP II dominates; for absolute minimum bulk, the Sheriff wins.
What does it weigh and what are the dimensions?
The Sheriff weighs exactly 5.6 ounces with an overall length of 5.75 inches and height of 3.75 inches. The 2.5-inch octagonal barrel contributes to the compact profile, while the cylinder measures 1.125 inches in diameter. These dimensions make it one of the smallest centerfire-capable revolvers available commercially.
Who is this NOT for?
This revolver is not for anyone seeking a primary defensive firearm or high-round-count training tool. The single-action mechanism requires manual cocking between shots, and the tiny sights make rapid acquisition challenging. If you need a first-line defensive weapon, consider something like the Stevens 334 in .308 Win for serious stopping power.
What's in the box?
The package includes the revolver, one five-round cylinder, and typically a basic nylon holster. Unlike larger firearms, you won't find cleaning kits or additional magazines—NAA assumes you understand this is a minimalist tool. The cylinder removal tool is integrated into the grip frame, which saves weight but requires careful handling.
Is the NAA Sheriff worth it at $312.99?
At $312.99, the Sheriff represents fair value for its niche role as an ultra-compact backup weapon. The stainless construction ensures longevity, and the mechanical precision exceeds what you'd find in similarly priced Saturday night specials. For recreational shooters who appreciate miniature engineering, it's priced appropriately, though the Stevens 555 Sporting Compact offers more practical fun for similar money.

Frequently asked questions
- Is it compatible with .22 LR ammunition?
- No, the Sheriff is chambered exclusively for .22 Winchester Magnum Rimfire (22 WMR). Attempting to fire .22 LR can cause dangerous pressure issues and cylinder alignment problems. NAA offers separate cylinder conversions for approximately $75, but they must be fitted by a qualified gunsmith.
- Does it fit in a standard pocket holster?
- Yes, the Sheriff's compact dimensions (5.75" long × 3.75" high) allow it to fit most small revolver holsters. NAA recommends their custom leather holsters for optimal retention, but any pocket holster designed for mini-revolvers should work. The rosewood grips may require break-in time with tight leather.
- How long does shipping take to FFL dealers?
- Most FFL shipments process within 3-5 business days after order verification and background check completion. Ironclad Armory uses UPS Ground for firearm shipments, with transit times varying by location. All shipments require signature confirmation at the receiving FFL.
- Can I return it if it doesn't fit my hand?
- Firearms sales are final once the transfer is completed at your FFL. We recommend handling similar-sized revolvers at a local dealer before purchasing. The Sheriff's grip circumference measures 3.25 inches—significantly smaller than full-size handguns.
- Does this work with common .22 WMR ammunition?
- Yes, the Sheriff cycles reliably with most major-brand .22 WMR ammunition including CCI Maxi-Mag and Federal Premium. We've tested with 40-grain JHP rounds achieving consistent ignition across 200-round sessions. Avoid reloads and subsonic loads, which may not generate sufficient pressure for reliable cycling.
