each maker has their own numbering/model/naming convention.
Caliber is used to relate the diameter of a projectile (bullet). Its possible for two projectiles to have the same diameter, but vastly different weights/masses. One bullet might be 3 times as long as the other, although both have the same diameter. Caliber is typically measured as hundredths of an inch. So a 38 Caliber implies a projectile with a diameter of 38/100th of an inch, or .38 Cal. Notice the leading decimal point in most caliber designations. .45ACP is 45/100th of an inch. ACP is a special, patented shape of round designed by the Colt company for its automatic pistols. ACP = Automatic Colt Pistol.

Designations given to orbitals, in the order atoms of increasing size require them.
No. There are, however, many planets discovered by a spacecraft called Kepler and given designations such as Kepler-69c.
No. Serial numbers aer NOT UNIQUE. They are intended to be unique to a given make and model- but a gun can be rebarreled to a different caliber.
Given its intended purpose, yes.
34 1 caliber is an an inch. so if it is .68 of an inch, its radius half: 34
No. Generally speaking, you can only use the correct caliber magazine for any given handgun, and .380 and 9mm are not interchangeable.
