Frequently Asked Questions

How do I know what type of ammunition my firearm uses?

The correct ammunition type for your firearm is always clearly marked on the firearm's barrel or frame. You must know what type of ammunition your firearm is chambered for, as each firearm is designed for a specific type.

What are the different designations for 9mm ammunition?

The 9mm Luger cartridge has several common designations: 9mm Parabellum (original military name), 9mm Luger (US commercial name), and 9x19 (European designation based on bullet diameter and case length).

Can a .357 Magnum revolver fire .38 Special ammunition?

Yes, many modern revolvers can chamber more than one type of ammunition. A .357 Magnum revolver can typically fire .38 Special cartridges, which are a shorter version of the Magnum round.

Is it safe to use Plus P ammunition in any firearm?

No, you cannot use Plus P ammunition unless your firearm was specifically designed to handle the increased pressure. Always consult your firearm's owner's manual or contact the manufacturer to confirm safety.

Should I use the same ammunition for target practice as for self-defense?

Not necessarily. For casual plinking or target practice, more affordable ammunition can be used. For self-defense or hunting, you should use ammunition specifically designed for those critical purposes.
