Every peson in the USA should own a revolver capable of shooting either .22 Rimfire or .38 Special. Owning one revolver for each is even better.
Why you ask?
Because they are so much fun for plinking. Not all shooting should be so serious.
Uncomplicated. Easy to use to teach new shooters.
No worries about reloading magazines until your thumbs are sore.
They are cheap to shoot.
You can get ammo anywhere. And lots of varieties. Low power, high power it all works the same.
And, in the case of the .38 Special, if you reload, there are more bullet styles available than any other handgun caliber.
PLUS, you don't have to chase down your brass or get it mixed up with Joe Blows super-dooper ++P+HV loads in casings that have only been reloaded about 50-75 times. You know. the ones that only have a few tiny cracks around the mouth.
But the fact that they're fun is still the best reason.
