That number of rounds can vary. Most of us are familiar with revolvers that hold six rounds. Some pistol magazines can hold up to 13 and more. I know of one revolver with a cylinder that holds nine rounds.
6, IIRC
It depends on the pistol make and model, and what it is chambered for. Most semi-autos nowadays hold at least 12 rounds. Most revolvers hold six.
None. No such gun.
A 22 caliber pistol holds a dose of 22 caliber ammo.
Normally 30 rounds per clip
A pistol typically has a magazine, which is a device that holds ammunition and feeds it into the chamber for firing. The term "clip" is often mistakenly used to refer to a magazine, but clips are used to hold rounds together for loading into a magazine, not as a feeding device themselves. In summary, pistols use magazines, while clips serve a different purpose in the loading process.
