Many people researching personal protection want an option that does not rely on conventional firearm ammunition. That is where non-lethal guns, also commonly described as less-lethal launchers, enter the conversation.
These CO2-powered platforms are designed to provide a less-lethal personal-protection option using compatible kinetic, training, marking, or chemical-irritant projectiles depending on the launcher and applicable laws.
If you are comparing current models, start with our Byrna non-lethal gun guide or browse the full Byrna launcher collection.
What Is a Non-Lethal Gun?
A non-lethal gun is a less-lethal projectile launcher designed as an alternative to conventional firearms. Rather than firing conventional firearm ammunition, these platforms typically use compressed gas such as CO2 to launch compatible projectiles.
The term “non-lethal” is commonly used by consumers, although less-lethal is generally a more accurate description because any projectile-launching device can potentially cause injury.
Depending on the launcher, compatible projectile options may include:
- Kinetic impact rounds
- Training and practice projectiles
- Marking rounds
- Chemical-irritant projectiles where permitted
How Do Non-Lethal Guns Work?
Many modern less-lethal launchers use compressed CO2 as their power source.
The basic operating process typically involves:
- Installing the correct CO2 cartridge for the launcher.
- Loading compatible projectiles into the appropriate magazine or feeding system.
- Preparing the launcher according to the manufacturer's instructions.
- Using the launcher only in accordance with safe-handling guidance and applicable laws.
Operating systems, caliber, capacity, velocity, CO2 requirements, and projectile compatibility can vary significantly between models, so users should review the specifications for their specific launcher.
What Types of Non-Lethal Guns Are Available?
Less-lethal launchers come in several configurations, from compact pistol-style platforms to larger launcher systems.
Pepper Ball Guns
Pepper ball guns are CO2-powered launchers capable of firing compatible projectiles from a distance. Depending on the launcher and ammunition, projectile options may include chemical-irritant rounds where lawful.
If this is the type of platform you are researching, browse our pepper ball guns for non-lethal self-defense.
Kinetic Impact Launchers
Kinetic launchers use compatible solid projectiles that rely primarily on physical impact rather than chemical irritation.
The practical effect of a kinetic projectile can vary based on the launcher, projectile type, distance, impact location, environmental conditions, and individual response.
CO2-Powered Less-Lethal Launchers
Modern Byrna platforms use compressed CO2 and are available in different calibers, sizes, capacities, and configurations.
Some Byrna platforms can use multiple compatible projectile types, making it important to understand the specific launcher and ammunition combination being considered.
Non-Lethal Gun vs. Less-Lethal Gun: Is There a Difference?
Consumers often use the terms non-lethal gun and less-lethal gun interchangeably.
“Non-lethal” is the more common search term, while “less-lethal” better reflects the fact that these products are not harmless and can potentially cause injury.
For that reason, responsible owners should treat a less-lethal launcher as serious personal-protection equipment and follow manufacturer instructions, safe-handling practices, training recommendations, and applicable laws.
Are Non-Lethal Guns Effective for Self-Defense?
Less-lethal launchers are designed to provide another personal-protection option, but no defensive tool can guarantee that a person will immediately stop, retreat, or react in a specific way.
Practical performance can depend on:
- Launcher model
- Projectile type
- Distance
- Accuracy
- Environmental conditions
- User familiarity and training
- The response of the person involved
For this reason, a non-lethal gun should be considered one possible component of a broader personal-safety or preparedness strategy rather than a guaranteed solution.
Why Are Byrna Less-Lethal Launchers Popular?

Non-Lethal Gun vs. Conventional Firearm
Non-lethal and less-lethal launchers operate differently from conventional firearms.
| Feature | Less-Lethal Launcher | Conventional Firearm |
|---|---|---|
| Power source | Often compressed CO2 | Conventional firearm ammunition |
| Projectile options | Kinetic, training, marking or irritant depending on platform | Conventional bullets |
| Primary design | Less-lethal personal protection, training or specialized use | Varies by firearm type and intended use |
| Regulation | Varies by launcher, projectile and jurisdiction | Subject to firearm laws and regulations |
Laws can vary significantly, so users should not assume that every less-lethal launcher or projectile is treated the same way in every jurisdiction.
Non-Lethal Guns for Home Defense
Some households consider less-lethal launchers as part of their home-preparedness planning.
Important considerations include:
- Safe storage
- Who may have access to the launcher
- Training and familiarity
- CO2 readiness and maintenance
- Projectile selection
- Applicable laws
For more detail, read our guide to pepper ball guns for home defense.
How to Choose a Non-Lethal Gun
Rather than choosing a launcher based only on appearance or advertised performance, compare the factors that affect practical ownership and use.
Consider:
- Launcher size
- Grip comfort
- Caliber
- Capacity
- CO2 system
- Compatible projectiles
- Storage requirements
- Training availability
- Local laws
- Intended application

Training and Responsible Ownership
Buying a less-lethal launcher is only one part of responsible ownership.
Owners should understand:
- Safe handling
- Loading and unloading
- CO2 installation and storage
- Projectile compatibility
- Routine maintenance
- Responsible storage
- Manufacturer instructions
Nakestores provides Byrna education and in-person training resources for customers who want additional familiarization with their equipment.

Are Non-Lethal Guns Legal?
Laws governing less-lethal launchers can vary by state, locality, launcher type, projectile type, age, possession, transportation, carry, and intended use.
Chemical-irritant projectiles may also be subject to additional restrictions in certain jurisdictions.
Customers should verify current local requirements before purchasing, carrying, transporting, or using any less-lethal launcher or projectile.
