Case of CRS regarding 9mm

Is a 9mm Luger the same as the 9mm for a Keltec or Taurus? Thanks

Ammo I mean

Whether you call it the 9x19mm, 9mm Luger, 9mm Parabellum, or 9mm NATO, it's the same cartridge. Same size, that is.

Thanks John

Yup. 9mm Luger (aka 9x19mm)is the standard here in the US. But there are several oddball eastern block 9mm calibers, like Makarov 9x18 mm so it can be confusing. Wikipedia explains this pretty well. The following are all synonyms for 9mm Luger:

9×19
9 mm
9 mm Luger
9 mm NATO
9×19mm
9×19mm NATO
9 mm Parabellum
9 mm Para
