CO₂ Air Pistols

Choose an air pistol by power system

How does a CO₂ air pistol work?

A CO₂ air pistol normally uses a carbon-dioxide capsule to propel the projectile. When the trigger is operated, the valve releases a controlled amount of gas that drives the pellet or steel BB through the barrel. There is no need to cock a spring manually or fill a compressed-air reservoir before shooting.

Performance depends on the design of the pistol, ambient temperature, ammunition, seal condition and whether the model incorporates Blowback. Always compare the specifications of the exact product variant rather than choosing solely by its external appearance.

Steel BBs or lead pellets

Not every CO₂ pistol accepts the same ammunition. Some models are designed for steel BBs, others for lead pellets, while selected pistols can use both through a compatible loading system.

Blowback and non-Blowback CO₂ pistols

Blowback describes the movement of the slide. It does not by itself determine the power or accuracy of the pistol. Barrel design, trigger quality, shot consistency, sights, ammunition and shooting technique also affect performance.

What does Full Metal mean?

The term Full Metal is commonly used for models containing a substantial proportion of metal components. It does not necessarily mean that every component is made of metal. The frame, grip panels or internal parts may use polymer or other materials.

A replica with a metal slide may provide a different weight and balance, while polymer components can help reduce overall weight. Always check the material specification of the exact variant.

CO₂ air-pistol brands

The CARBIN range includes CO₂ pistols and licensed replicas from Gamo, Umarex, Glock, Beretta, SIG Sauer, Smith & Wesson, Crosman, CZ, HK, Norica and other specialist manufacturers.

Brand alone does not determine the specification. Blowback, metal slides, detachable magazines, rifled barrels and compatible ammunition can vary between models from the same manufacturer.

Accessories for CO₂ air pistols

Consumables and accessories must match the exact pistol, calibre and ammunition type.

• CO₂ capsules: check the required capsule format and manufacturer’s instructions.
• Lead pellets or steel BBs: use only ammunition approved for the pistol.
• Spare magazines: verify the model, generation, calibre and projectile type.
• Targets and pellet traps: select equipment suitable for the ammunition being used.
• Eye protection: recommended whenever the pistol is being used.
• Maintenance products: use products suitable for CO₂ valves and seals.

CO₂ air-pistol maintenance

• Do not store the pistol for extended periods with a pierced CO₂ capsule installed.
• Use only lubricants suitable for the seals in a CO₂ system.
• Do not introduce unsuitable mineral oils into the valve or seals.
• Keep the barrel and magazine clean and free from debris.
• Check seals and moving components periodically.
• Store the pistol unloaded, without ammunition, in a dry and secure place.

Always follow the manufacturer’s instructions. If you notice a gas leak, damaged seals or irregular operation, stop using the pistol until the cause has been assessed.

Frequently asked questions about CO₂ air pistols

Do all CO₂ air pistols shoot lead pellets?

No. Some models use lead pellets, while others are designed for steel BBs. Selected systems can accept both projectile types. Always follow the ammunition specification provided by the manufacturer.

What is the difference between Blowback and non-Blowback?

A Blowback model uses part of the gas to move the slide. A non-Blowback pistol does not use CO₂ for this movement, so the two systems provide different handling characteristics and gas consumption.

How many shots does a CO₂ capsule provide?

There is no figure that applies to every pistol. Shot count depends on the model, temperature, shooting pace, seal condition and whether the pistol incorporates Blowback.

Is a Full Metal pistol made entirely from metal?

Not necessarily. The term normally indicates a substantial use of metal components, but the frame, grips or internal parts may still use polymer or other materials.

Can a pierced CO₂ capsule be left in the pistol?

It is not advisable to store the pistol for a long period with a pierced capsule installed. Continuous pressure may affect the seals. Follow the manufacturer’s procedure when removing the capsule.

What should I check before buying a spare magazine?

Check the brand, exact model, generation, calibre and ammunition type. Visually similar pistols may require different magazines.
