North American Arms has long made their name producing ultra-small single-action revolvers in rimfire cartridges. Their Black Widow offering adds an oversized rubber grip and proper 3-dot sights, making this diminutive .22LR/.22 WMR revolver much easier to hold on to and shoot accurately. While their use case is definitely limited, their concealability cannot be understated. At under 10 ounces with extremely small overall dimensions, these guns simply disappear inside pockets or other clothing.
