Why single shot pistols?
Because there is no law, rule, or reason why all handguns should be repeaters! Not every handgun needs to be best suited for personal defense. Celebrate diversity!
Single shots are for sport. Wheather that sport is hunting, formal target shooting or informal plinking.
Single shots are also lighter than repeaters in the same calibers. And they are available in a wide range of cartridges that repeaters are not.
AND, they're FUN!
