Which gun should I choose: an air gun or a revolver chambered for a Flobert cartridge? – this is a common question asked by all beginning shooters and gun enthusiasts. Both types of weapons are available for purchase without the need for a special permit from the Ministry of Internal Affairs of Ukraine (subject to certain conditions). They have similar calibers, but differ significantly in muzzle energy, projectile velocity and weight, functional features, operating cost, and overall shooting experience.
In this article, we will discuss which is better: an airgun or a weapon chambered for the Flobert cartridge, their advantages, and the nuances of their use.
Comparing an airgun and a Flobert pistol is quite difficult, as they differ significantly in design and operating principle.
Structurally, a shot in Airguns operate using compressed air, which acts on a bullet and propels it out of the barrel. Depending on the mechanism, there are two types of airguns: spring-piston (pumped) and gas-cylinder. Airgun ammunition is 4mm iron balls.
Advantages and features of airguns:
Other advantages of airguns include quiet operation and good accuracy, as well as the ability to choose a model that accurately replicates the performance of renowned gun brands.
The disadvantages of airguns include their low projectile velocity (balls), typically no more than 140 meters per second, and low effectiveness (the damaging effect of an air pistol is typically a hematoma at the point of impact). That is, such weapons are primarily suitable for deterrence and, in the event of a real threat, can only exacerbate the situation.
A weapon chambered for the Flobert cartridge is also not lethal. It uses small-caliber, specialized 4-4.5 mm rimfire ammunition. It differs significantly from pneumatic guns in both its operating principle and maintenance requirements. Structurally, it is very similar to firearms. However, the cartridges do not have a propellant charge; instead, a pyrotechnic mixture is used, which is rimmed within the rim of the cartridge case base. The Flobert model determines the operating algorithm, namely, whether the hammer must be cocked before firing, or whether firing is automatic – Self-cocking.
Advantages of pistols chambered for the Flobert cartridge over airguns and other types of shotguns:
As for the downsides, it’s worth noting that the Flobert and its ammunition are more expensive than airguns. The pistol also has a lower accuracy rate, and the cylinder holds a limited amount of ammunition.
Giving a universal answer to the question of which is better and more powerful – an airgun or a Flobert – is difficult, since these characteristics primarily depend on the type of pneumatic system and the specific weapon model. Let’s take a closer look.
Let’s look separately at the characteristics that affect the power of both types of weapons.
First, the weight of the projectiles. If we consider the basic models (4mm versus 4.5mm), the power of the ammunition will be comparable. Ammunition for the Flobert pistol is heavier, so its kinetic energy at range and penetration are slightly higher, which means this will also affect the effectiveness of its use.
Second, velocity. If we are talking about light types of airguns (for example, a gas-cylinder pistol), the velocity is often higher. Hunting rifles use heavier bullets to avoid stabilization. In Flobert pistols, the bullet speed is moderate, but due to its greater weight, it receives more momentum.
Thirdly, muzzle energy. Calculated using the formula: \(E = \frac{m \cdot v^2}{2}\), where \(m\) – mass, and \(v\) – speed. Since Flaubert bullets are heavier, they receive greater penetrating force compared to air pistols.
Let’s look at typical indicators of muzzle energy, velocity and projectile mass for various categories of weapons:
| Options | Flaubert revolver (4 mm) | Pneumatic gun (CO2, 4.5 mm) | Air rifle (PPP/PCP, 4.5 mm) |
| Typical projectile | Lead projectile, 0.5 g | Steel ball BB, 0.35 g | Lead bullet, 0.5 – 0.68 g |
| Initial speed | 160–210 m/s | 100–130 m/s | 170–320+ m/s |
| Muzzle energy (calculated) | 8.10 – 11.03 J (for 0.5 g at 180-210 m/s) | 2.52 J (for 0.35 g at 120 m/s) | 7.66 – 26.66 J(for 0.5 g at 175 m/s to 0.68 g at 280 m/s) |
According to the data given in the table, the Flaubert revolver is more powerful than CO2 pneumatics. However, Flaubert is less powerful than spring-piston air rifles, which are capable of developing muzzle energy 2-3 times higher.
In pistols chambered for the Flaubert cartridge, one of the main parameters affecting muzzle energy is – This is the tightness of the gap between the drum and the barrel. In high-quality revolvers (for example, Alfa mod.441), this gap is minimal, which makes it possible to achieve the declared energy of 7.5-10 J. In inexpensive options, the energy can be reduced to 5-6 J. The choice of cartridge is also important: for example, ammunition from Sellier & Bellot and RWS Dynamit Nobel often provide more consistent speed and energy performance compared to some Turkish equivalents.
In pneumatics, power directly depends on the type of system. Gas pistols (such as replicas МР-654К or SAS Makarov) are characterized by small 2-3.5 J. Compression pistols (such as Beeman P17) can reach 5-7 J. And powerful air rifles, such as Hatsan 125 (PPP) or PCP systems give 20-30 J, which allows them to work effectively at distances up to 50–70 meters. For comparison, the effective distance for Flaubert is usually limited to 10-15 meters.
Accuracy – one of the key parameters for any small arms. Air guns (such as rifles and high-quality compression pistols) have fairly high shooting accuracy. High-quality Diabolo-type air bullets have better aerodynamics and flight stability, unlike the round lead balls used in Flaubert cartridges. The rifled barrel of an air rifle, combined with the absence of strong vibrations from the explosion of the primer, makes it possible to achieve high accuracy (1-2 cm at 25 meters).
When it comes to pistols chambered for the Flobert cartridge, their independence and simplicity are key. There’s no need to stock up on CO2 cartridges or pumps, nor is it necessary to break the barrel after each shot, as with some types of airguns. You simply load the cylinder and fire. However, the Flobert cartridge has a specific drawback: it gets dirty quickly. The primer is caustic, and its combustion products almost immediately leave carbon deposits in the barrel and cylinder. This means that a thorough cleaning is necessary after each use (20-50 shots). Otherwise, the accuracy and stability of the weapon quickly deteriorate.
The cost of shooting and maintenance often become decisive when choosing a gun for recreational shooting or training.
Shooting with airguns is one of the most inexpensive. A pack of 500 lead bullets costs significantly less (approximately 250-800 UAH in 2026) than 10-20 Flobert cartridges. Airgun maintenance is minimal: periodic lubrication of the seals and barrel cleaning are required approximately every 500-1,000 shots.
Shooting a gun chambered for Flobert cartridges is more expensive (around 2,000 UAH for a pack of 200, 4 mm). This means that in terms of operating costs, Flobert can be compared to small-caliber firearms. The same applies to its maintenance: it is more labor-intensive, as it requires mandatory, thorough cleaning and lubrication after each shooting.
What is better to choose – Whether you choose an air pistol or a revolver chambered for the Flobert cartridge depends largely on your goals, whether it’s for training and shooting recreationally, or for gaining a realistic experience with a gun.
If you want to shoot a lot and frequently at targets, cans, or other objects, improving your accuracy and firearms skills, an air pistol is definitely the way to go. Thanks to the low cost per shot, you can enjoy shooting without significantly impacting your budget. Airguns are also excellent for learning to shoot and mastering gun handling rules due to the lack of strong recoil and loud noises.
If you are looking for the most realistic experience, close to shooting a firearm, the Flobert is guaranteed to be the best choice.
The sound of the shot, the slight recoil and muzzle flash, and an understanding of the mechanics of a revolver are what you get when using a gun chambered for Flobert cartridges. This is an excellent opportunity to become more familiar with the rules of handling a revolver. In addition, such a weapon A good option for purchasing as a collector’s item, or simply for those who value authenticity and aesthetics.
Regarding the legal aspects of using airguns and weapons chambered for the Flobert cartridge, this is regulated in Ukraine by various regulations, including Order No. 622 of the Ministry of Internal Affairs “On Approval of the Instructions on the Procedure for the Manufacture, Acquisition, Storage, Registration, Transportation, and Use of Firearms, Airguns, Bladed Weapons, and Other Types of Weapons, as well as Ammunition.” Please note the following current regulations as of 2026.
For pneumatic weapons.
Pneumatic weapons up to and including 4.5 mm caliber may be purchased without a permit by persons aged 18 and over.
With a permit and registration with the Ministry of Internal Affairs, it is possible to purchase pneumatic weapons with a caliber greater than 4.5 mm and with a bullet velocity exceeding 100 m/s.
For weapons chambered for the Flobert cartridge (4 mm).
Weapons chambered for the 4 mm Flobert cartridge and with a muzzle energy of 7.5 J are not classified as firearms. They may be freely purchased by persons aged 18 and over.
Additionally, it is important to consider the legal nuances regarding carrying and use. Free sale does not imply the right to freely carry and use them anywhere. Carrying an air gun or a Flobert pistol openly, loaded, or using them in public places (on the streets, in parks, where there are crowds of people) is classified as a violation of public order (Articles 173 or 174 of the Code of Ukraine on Administrative Offenses) and may entail administrative liability, including a fine and confiscation of the weapon.
Using pneumatics or Flobert for self-defense is not highly effective. Their low stopping power may not be sufficient to stop aggression, but it can still lead to serious legal consequences for the defender (exceeding the limits of necessary self-defense).
Any attempts to modify a weapon chambered for the Flobert cartridge or an airgun to increase its power, as well as converting it to live ammunition, are criminally punishable acts.
For clarity, we have prepared a general table comparing the main parameters and conditions of use of airguns and weapons chambered for Flobert cartridges:
| Parameter | Airguns (CO2 / PCP / PCP) | Weapons chambered for Flaubert (4 mm) |
| Operating principle | Compressed gas / air | Capsule composition (pyrotechnic) |
| Ammunition type | Lead bullets (Diabolo), steel balls (BB) | Flaubert unitary cartridge 4 mm (lead ball) |
| Typical energy | 2–3.5 J (CO2 gun), 7.5–30+ J (PPP/PCP rifle) | 7.5–10 J (revolver) |
| Accuracy | High (especially for rifles and high-quality pistols) | Medium (effective at distances up to 10–15 m) |
| Stability | High (depends on the quality of the weapon and ammunition) | Medium (sensitive to ammo quality and contamination) |
| Reality | Low (no pop, flash, or recoil) | High (characteristic sound, flash, slight recoil) |
| Cost per shot | Very low | High |
| Noise | Quiet (especially with (silencer) | Loud bang |
| Recoil | Virtually absent | Light, noticeable |
| Maintenance | Minimal (periodic cleaning and lubrication) | Regular and thorough cleaning of carbon deposits |
| Use scenarios | Recreational shooting, sports, training Accuracy, basic training | Collecting, imitation shooting, familiarization with revolver mechanics |
Let’s summarize. Airguns (especially rifles or high-quality compression pistols) are ideal for economical, accurate, and frequent shooting as part of training, sport, or recreation. They allow you to hone your skills without significant financial outlays on ammunition and with minimal maintenance requirements.
The Flobert pistol guarantees the most realistic imitation of a firearm and the characteristic feel of a shot. However, it is important to consider the higher price of ammunition and the need for regular, thorough maintenance.
Regardless of your choice, always remember about safety and responsible handling of any type of weapon, and strictly comply with current Ukrainian legislation. The easiest way to gain the necessary weapons handling skills and master accurate shooting techniques is at the Darwin Club.
No, a pistol chambered for 4mm Flobert cartridges is not considered a firearm and can be purchased without a special permit.
Yes, but it should be noted that such a weapon has a greater psychological effect than serious stopping power.
Airguns are significantly cheaper to operate than Floberts, thanks to the relatively low cost of the gun and ammunition.
Cleaning is required after each shooting. After use, the primer composition leaves a caustic residue in the barrel, which, if not thoroughly cleaned, will quickly lead to corrosion in the barrel, and eventually failure.
You can officially purchase an airgun or pistol chambered for the Flobert cartridge after reaching the age of 18.
The effective range of the short-barreled Flobert revolver at targets is approximately 10-15 meters.
