Small - regular - not the magnum
9mm Parabellum cartridges (9mm Luger) HAVE small pistol primers. For some applications such as submachine guns with a free floating firing pin, a harder primer may be used. However, in most applications, the same primer used in .38 Special would also be used in a 9mm.
No. They are the wrong diameter, 45 you need large pistol/large rifle sized primer diameter. Also rifle primers are thicker and require a heavier primer strike that some pistols can not deliver. My Springfield XDM only intermittently can set off a small rifle primer when used to load 9mm.
probably If the pistol is designed for 9mm Luger, 9mm Para, or 9x19, yes.
The 9mm pistol would have the higher decibel rating.
No
Most likely a 9mm with a suppressor
9mm MKV is not the same as 9mm Luger.
The 9mm Parabellum is longer than the .380 ACP (also called the 9mm Short) They do not interchange.
Small Pistol Primers are used for small caliber pistols, any of the various 9mm calibers such as the .380, the 9mm luger, the 9x18 makarov, the .38 special, the .32 acp, the .25acp etc. and even some larger calibers such as the .40 S&W. Large caliber pistol primers are used in .45 caliber and larger. Still other calibers, such as the .357 Magnum for instance, require primers known as magnum primers.
