What Blank Ammo Do I Need? A Beginner’s Guide to Blank Ammunition

What Kind of Blank Ammo Do I Need?

One of the most common questions we get is:
“What kind of blank ammo do I need?”

The short answer? It depends.

Blank ammunition comes in many different calibers and types, and the names can be confusing. This guide breaks down the most common types of blank ammunition and explains how to choose the correct blanks for your firearm.

Blank Cartridges Are Not Universal

Blank cartridges are not one-size-fits-all. Different blank-firing guns are designed for specific types of ammunition, even when the caliber names sound similar.

Using the wrong blank ammunition can cause malfunctions or damage to blank-firing guns, so it’s important to identify your firearm or replica before purchasing blanks.

Where to Start

The most important rule when choosing blank ammunition is:

Always use the blank ammunition specifically designed for your blank-firing gun or real firearm.

Typically, the required caliber is stamped onto the side of the firearm. From there, the next step is identifying what type of gun you’re using.

Step 1: Are You Using a Replica or a Real Firearm?

If You’re Using a Replica (Blank-Firing Gun)

Blank-firing replicas can be easily identified by their orange tip at the front of the barrel. Start by identifying the type of replica:

Blank-firing replicas are clearly marked with the correct caliber, and this marking should always be your primary reference.

However, there are several types of blank cartridges—especially those labeled “9mm”—that can cause confusion:

  • 9mm RK – Commonly used in blank-firing revolvers and often referred to as .380 stage blanks. This is a short .38 cartridge designed specifically for blank-firing replicas.
  • .22 caliber blanks – Used in some blank-firing revolvers and starter pistols.
  • 9mm PAK – Typically used in semi-automatic blank-firing pistols. If your replica uses this type, it will usually be clearly marked “9mm PAK.”
  • 8mm PAK – Less popular than 9mm PAK but still commonly used today.

If you’re unsure, check the markings on your replica or refer to the manual included with your purchase. When in doubt, consult a qualified professional.

If You’re Using a Real Firearm

If you’re using blank ammunition in a real firearm, the general rule is simple:

Match the blank caliber to the firearm’s caliber.

Examples:

If you have any uncertainty, consult a professional before use.

Final Note: Cycling Semi-Automatic Firearms

Blanks do not always produce enough pressure to cycle a semi-automatic firearm.

If you need the firearm to cycle automatically, you may need to install a blank-firing barrel or blank-firing adapter. Always follow manufacturer guidelines for proper setup and safe operation.
