Pocket Handgun: Small 9mm Auto or 642 Airweight?
The NAA revolvers made a lot more sense before good, tiny .32 pistols became widely available. At least the 1 1/8 inch .22 lr. is smaller than any semiauto, and significantly smaller than some pocket .22 or .25 guns.
They are reliable, unlike some of these tiny semiautos.
They can be carried safely with the hammer lowered into a notch in the cylinder between chambers. Some tiny single action semiautos might not have the same level of safety.
They have surprisingly high intrinsic accuracy, although converting that to practical accuracy is not easy. The boot grips or slip on rubber grip go a long way towards preventing recoil from compromising accuracy.
They still make some sense if one needs the absolute smallest, lightest gun available.
