Walther CO₂ Pistols: German Heritage, Precision and Iconic Air Pistols
Walther CO₂ pistols bring together one of Germany's most recognised firearms names and the versatility of modern CO₂-powered airguns. From target-oriented pellet pistols such as the legendary CP88 to realistic models such as the PPK/S, the Walther range offers very different shooting experiences within the same brand.
At Carbin you can find Walther CO₂ pistols in 4.5 mm (.177), including models designed for Diabolo pellets as well as pistols intended for steel BBs.

Why Choose a Walther CO₂ Air Pistol?
One of the strengths of the Walther CO₂ range is that it does not follow a single concept. Different models are designed around different priorities: accuracy, shooting feel, classic styling, modern ergonomics or mechanical realism.
The CP88 family, for example, uses an 8-shot rotary magazine and Diabolo pellets, making it particularly interesting for recreational target shooting. The PPK/S follows a very different philosophy, combining steel BBs with Blowback action for shooters who place greater value on realistic operation.
This distinction is important when choosing a CO₂ air pistol: the most realistic pistol is not necessarily the one best suited to precision shooting, and a fixed-slide pellet pistol can offer advantages that a Blowback replica does not.
Walther and Umarex: CO₂ Pistols with an Authentic Identity
Walther has a particularly strong presence in the Umarex airgun portfolio. This relationship has made it possible to reproduce several well-known Walther platforms as CO₂-powered air pistols, while retaining many of the visual and ergonomic characteristics associated with the original designs.
That is why names such as Walther CP88, PPK/S and PPQ have become familiar not only to firearms enthusiasts, but also within the airgun and recreational shooting community.

Specifications may vary between versions. Always check the individual product page before selecting pellets, BBs or accessories.
Walther CP88: One of the Classic CO₂ Pellet Pistols
The Walther CP88 4" CO₂ air pistol has become one of the best-known models in the Walther airgun range.
Its formula is very different from that of many modern Blowback replicas. It uses an 8-shot rotary magazine, 4.5 mm (.177) Diabolo pellets and a fixed-slide design, with a clear emphasis on controlled recreational shooting.
Its metal construction, adjustable rear sight and single/double-action trigger contribute to the traditional feel that has made the CP88 such a recognisable name among airgun enthusiasts.
What Is the Difference Between the Walther CP88 4" and CP88 6" Competition?
The most obvious difference is the barrel configuration.
The standard CP88 uses a 4-inch format, while the Walther CP88 6" Competition extends the platform with a longer Competition configuration.
Both retain the core CP88 concept: CO₂ power, 4.5 mm Diabolo pellets, an 8-shot rotary magazine and a non-Blowback system.
For shooters primarily interested in target shooting, the Competition version is therefore the natural model to consider alongside the standard CP88.
Walther PPK/S CO₂: Blowback and Steel BBs
The Walther PPK/S CO₂ air pistol represents a completely different approach.
Instead of focusing primarily on Diabolo pellets and a fixed action, the PPK/S uses 4.5 mm steel BBs and Blowback action. The moving slide adds mechanical movement to the shooting cycle and makes the experience noticeably different from that of a CP88.
This makes the PPK/S particularly interesting for plinking, replica enthusiasts and collectors who value the character and operation of an iconic Walther design.
Does Blowback Make a CO₂ Pistol More Accurate?
Not necessarily. Blowback and accuracy describe two different characteristics.
A Blowback system uses part of the available CO₂ to cycle the slide. Its principal attraction is the additional movement and more dynamic shooting experience.
A fixed-slide CO₂ pellet pistol can instead devote its design more directly to consistent pellet delivery and target shooting. This is one reason why models such as the CP88 do not need Blowback to fulfil their intended role.
Walther PPQ CO₂: Modern Ergonomics with a Rifled Barrel
The Walther PPQ CO₂ pistol combines contemporary styling with a different technical approach from the PPK/S.
It features a rifled steel barrel, 8-shot capacity, fixed slide, adjustable sights and an accessory rail. Rather than using Blowback, the PPQ focuses on a straightforward CO₂ shooting system in a modern Walther format.
It is therefore an interesting middle ground for shooters attracted to contemporary pistol ergonomics but who do not specifically require a moving slide.
Steel BBs or Diabolo Pellets: Which Should You Choose?
This is one of the most important distinctions when comparing Walther air pistols.
Diabolo pellets are the natural choice for models such as the CP88, where a rifled barrel and rotary magazine form part of a more target-oriented system.
Steel BBs, on the other hand, are used in models such as the PPK/S, where rapid recreational shooting and replica-style operation are more important.
Both can be 4.5 mm (.177), but a 4.5 mm steel BB and a 4.5 mm Diabolo pellet are not the same type of ammunition. Always use the ammunition specified by the manufacturer for the individual pistol.

Which Walther CO₂ Pistol Is Best for Target Shooting?
If target shooting and accuracy are the priority, the first models to compare are the Walther CP88 variants.
Their use of Diabolo pellets, rotary magazines and non-Blowback operation gives them a different character from replica-focused BB pistols.
The CP88 6" Competition is particularly relevant for shooters looking for the longer Competition configuration, while the standard CP88 4" retains the classic and more compact format.
Which Walther CO₂ Pistol Offers the Most Mechanical Realism?
Within the current Carbin Walther CO₂ collection, the PPK/S is the clearest choice if Blowback operation is a priority.
Its moving slide and steel BB system create a more dynamic shooting experience than the fixed-slide CP88 and PPQ platforms.
This does not make it inherently better or worse: it simply serves a different purpose.
Which Walther CO₂ Pistol Should You Choose?
| If your priority is... | Consider | Why? |
|---|---|---|
| Classic target shooting | CP88 4" | Diabolo pellets, 8-shot rotary magazine and proven CP88 platform |
| A more precision-oriented CP88 | CP88 6" Competition | Longer Competition configuration while retaining the CP88 concept |
| Classic styling with a distinctive finish | CP88 Nickel | CP88 platform with nickel finish |
| Blowback and replica character | PPK/S | Moving slide, steel BBs and iconic Walther styling |
| Modern ergonomics | PPQ CO₂ | Contemporary format, rifled barrel and accessory rail |
| Simple recreational shooting | CP Sport | Straightforward pellet-pistol concept for recreational use |
Frequently Asked Questions About Walther CO₂ Pistols
Are Walther CO₂ pistols air pistols?
Yes. A CO₂ pistol is a type of air pistol. Instead of using a spring, gas ram or pre-charged pneumatic reservoir, it uses compressed carbon dioxide as its power source.
What calibre are Walther CO₂ pistols?
The Walther CO₂ pistols in this collection are 4.5 mm (.177) calibre. However, calibre alone does not tell you which ammunition to use: depending on the model, the pistol may be designed for Diabolo pellets or steel BBs.
Do all Walther CO₂ pistols have Blowback?
No. Most models in the current range use a non-Blowback system. Blowback should therefore be considered a specific feature rather than a standard characteristic of every Walther CO₂ pistol.
What pellets does the Walther CP88 use?
The Walther CP88 is designed for 4.5 mm (.177) Diabolo pellets and uses an 8-shot rotary magazine.
Does the Walther PPK/S use pellets or BBs?
The Walther PPK/S uses 4.5 mm steel BBs. It should not be confused with pellet-firing models such as the CP88.
Is the Walther PPQ CO₂ a Blowback pistol?
No. The Walther PPQ CO₂ in the current range uses a fixed slide. It combines this configuration with an 8-shot system, rifled steel barrel and accessory rail.
Are steel BBs and .177 pellets interchangeable?
No. Although both may be described as 4.5 mm or .177 calibre, steel BBs and Diabolo pellets have different shapes and characteristics. Always follow the ammunition specification for the individual air pistol.
Which is better: Blowback or non-Blowback?
Neither system is universally better. Blowback is attractive when movement and replica-style operation are priorities, while non-Blowback designs are often preferred when simplicity, CO₂ efficiency or target-oriented shooting matter more.
