Very simply, you have to know what caliber your gun is. If you don't know, take it to a reputable gun store and ask them to look at it.
Yes.
Sporting goods stores, gun stores, or gun ranges normally have handgun ammo. As an aside, handgun ammo is in short supply at the current time.
In some states. like OH, you can be 18. Oddly, though, you can't carry it or buy "pistol; ammunition" until 21. So it beats me what they expect you to do with it, Maybe get a .44-40 and buy "rifle" ammunition?
Yes, in the US. Federal law requires you to be 21 to purchase ammunition for a handgun. .
