The NAA Pug Duke is a 5-round revolver chambered in .22 WMR with a 1-inch barrel and a black and silver finish. At 0.4 lbs, it is one of the lightest and most compact revolvers available in this caliber. That combination of weight and barrel length makes it a pocket or backup gun first and foremost.

Detailed Features 

At 1 inch of barrel, the .22 WMR delivers more energy than .22 LR but is still a light-recoiling, manageable round -- a realistic choice for shooters sensitive to stronger calibers or those using this as a deep-concealment backup. Five rounds is a real limitation, but the gun is genuinely pocketable in a way that larger-capacity options are not. The black and silver finish holds up to daily carry wear. 
 

Usage 

This revolver suits concealed carry as a backup gun, light field use on small game, or recreational range shooting. It is straightforward to operate, which makes it accessible to beginners, though the short sight radius and small frame require practice to shoot well.

Feedback on the NAA Pug tends to split along predictable lines. Owners who bought it as a pocket or backup gun are generally satisfied -- the compact size and light weight are its core appeal, and it delivers on both. The .22 WMR caliber is seen positively for its lower recoil and ease of shooting, especially for new shooters. Build quality and the distinctive black/silver finish get consistent praise.

The main criticisms center on stopping power and trigger pull. Some owners feel .22 WMR is underpowered for self-defense against larger threats, and the trigger is heavier than expected, which can hurt accuracy at this already-short barrel length. Price is generally seen as fair for what you get. Most who bought it as a fun range gun or last-ditch backup are happy with it; those expecting primary-carry performance are less so.
