I once bought this little air gun, unfortunately someone stole it from me... a big regret but... as for this Beretta, I recommend it to everyone, great equipment. I bought it around 2005 if I remember well and it was new to the market then and, unfortunately, practically the most expensive, but... I never regretted it and now I plan to buy it again when it's available. I didn't buy it online, only in physical partner stores. Forget the gas... loads of fun, it works beautifully and the possibility to load different pellets. I shot both BBs and Diabolo. Something interesting for everyone, whatever you like. I fully recommend.. and if you think the gas is too expensive, buy something else.

Made in Japan, this air pistol is a replica of the Beretta Px4 Storm. It operates using compressed carbon dioxide from a 12-gram CO2 cartridge, which is inserted in the grip just behind the magazine well. A single gas cartridge enables around 60 shots, with a velocity of up to 115 m/s.
Constructed from a blend of polymers and metal, the pistol combines strength with light weight—an approach refined for almost 30 years. The trigger, adjustable safety, hammer, barrel, and internal parts are made from metal. The frame, grip, and trigger guard (hilt) are fabricated from durable polymer.
Featuring a rifled barrel measuring 105 mm and equipped with a revolver-style magazine, this air pistol is capable of firing pellets (type Diabolo). Users can select different pellet types depending on the application: target, penetration, or fragmentation.
A uniquely designed magazine with an integrated connector includes two rotary rings, each accommodating 8 pellets. After discharging the first ring for eight shots, the magazine rotates 180 degrees for another eight shots. The magazine release button is positioned at the base of the grip to enable extremely fast reloading—achievable in just 2 seconds—without the need to reposition your hand.
The advanced trigger mechanism facilitates SA/DA (Single Action/Double Action) operation, allowing either manual cocking with the slide or thumb, or double-action trigger pull to cock the metal hammer. The system features a Blow-Back system, which cycles the heavy metal slide backward after each shot, automatically cocking the hammer. This mechanism allows for increased firing speed and makes the pistol suitable for training by those familiar with firearms.
Trigger safety is ensured via an adjustable lever situated above the grip on the right side. The lever also functions as a hammer decocker; setting it to S (safe) securely lowers the cocked hammer, in line with top-tier pistol safety standards.
Sights include a fixed front and rear sight enhanced with white dots to replicate tritium-style sights popular on military and police handguns. A mil std 1913 accessory rail (picatinny) located under the barrel allows for effortless mounting of a tactical laser or flashlight.
Grip surfaces—including both the grip panels and slide serrations—are textured for complete control. The checkered grip surface prevents slipping, while deep serrations above the safety levers on both sides of the slide make racking the slide simple and secure, even when wearing tactical gloves.
Attention to detail in the replica closely matches the original firearm, with the iconic Px4 Storm logo and durable markings denoting its 4.5 mm caliber for pellets. The design is exceptionally compact, avoiding protruding features or sharp edges.
The Px4’s distinctive frame was engineered by the renowned Italian design firm Giugiaro Design, world-famous for collaborations with automotive legends like Audi, Alfa Romeo, Lancia, Maserati, and Ferrari. Other firearms in the xx4 family include the Cx4 (Carbine X4) and Rx4 (Rifle X4).

I've had this Beretta for many years. Everything is in very good condition (just need to lubricate it). Surprisingly, it doesn't jam. The slide moves smoothly. It uses gas quite quickly, but that's not a problem. It's a pity the slide doesn't lock back when the magazine is empty. Maybe that's changed in the new models. Due to the threaded barrel, I recommend using Diabolo pellets.
-
A pleasant surprise, accurate and realistic this gun. The only downside is it quickly consumes CO2 to function normally. I RECOMMEND
-
The gun does not jam and looks nice visually.
-
Very good pistol. Good quality and affordable price. I recommend it.
-
A bit weak but generally gets the job done.
-
Neat, fits very well in the hand, sufficiently accurate. The downside for me is the way the gas capsule is mounted. The small knurl you have to turn before the latch tightens the gas. Overall impression and functionality 4/5, capsule assembly 1/5.

Hello. Great replica for Diabolo pellets. Strong blowback. Without the magazine and CO2 supply, you can practice dry shooting. Accurate, reasonably loud. The fact that the slide does not stay in the rear position is due to the use of rotary magazines and for me it's not a flaw, you can use it for reload training.
-
This pistol can easily compete with newer models with blow-back on Diabolo pellets. It fits well in the hand, does not jam, is powerful, sufficiently accurate, and the recoil is distinctly felt, it fires loudly. The price is much lower than rivals, but the additional magazines are disproportionately expensive. The slide not staying in the rear position after the last pellet has been fired is a feature, not a flaw of this type of pistol. On the downside, I would mention the safety switch not matching the original and the way the CO2 capsule is loaded.
-
Quite accurate, nice blowback. Fits well in the hand. Real gas consumption is about one cartridge for three magazines. Overall, I recommend it.
-
The air gun is very accurate. Shooting is a lot of fun.
-
The pistol matches the price. :-)
-
I bought the Beretta used, probably about a year old. I had the barrel checked and the rifling is in good condition. It shoots great and its recoil is impressive, but as a trade-off, it uses a lot of gas. Overall, I am satisfied.
-
I bought this air gun a week ago. My first impressions after this period are not very satisfying. I read that one CO2 cartridge is enough for about 60-70 shots. Unfortunately, you can feel the power drop after just 20 shots. On the plus side, it looks good and has blow-back. The accuracy of the gun is average.
