Beretta PX4 Storm .177 Pellet Pistol
Does the Umarex Beretta PX4 Storm shoot BBs or pellets?
The Umarex Beretta PX4 Storm shoots both .177 steel BBs and .177 pellets. It uses a dual-ended 16-shot magazine, with an 8-shot rotary clip on each end, so shooters can use either ammo type depending on how they want to train or shoot recreationally.
What type of CO2 does the Beretta PX4 Storm use?
The Beretta PX4 Storm uses a standard 12 gram CO2 cartridge loaded in the grip. Many owners keep extra Umarex 12g CO2 cylinders (https://www.umarexusa.com/12g-co2-cylinders-12ct) on hand so they can keep shooting without interruption.
How many shots can you get from one CO2 cartridge?
Shot count can vary based on temperature, shooting pace, and whether you are trying to maintain peak blowback performance, but most buyers are really asking whether one cartridge gives enough shooting time for a full session. For the best consistency, use clean 12g CO2 cylinders (https://www.umarexusa.com/12g-co2-cylinders-12ct) and avoid letting the pistol sit for long periods with a charged cartridge installed.
What is the magazine capacity of the PX4 Storm?
The Beretta PX4 Storm uses a 16-shot dual-ended magazine. Each end holds an 8-shot rotary clip, which is one of the reasons this model stands out from many other CO2 pistols.

Does the PX4 Storm have blowback action?
Yes. The Umarex Beretta PX4 Storm has blowback action for a more realistic shooting experience. That added movement helps make it more appealing for replica fans and informal training than many non-blowback CO2 pistols.
Is the Beretta PX4 Storm realistic?
Yes. The PX4 Storm is a licensed Beretta replica designed to deliver a more realistic handling and shooting feel than a basic entry-level air pistol. Buyers who want a replica-style CO2 pistol often choose it because it combines recognizable Beretta styling with blowback action and a firearm-inspired grip profile.
Is the PX4 Storm better for target shooting or backyard plinking?
The Beretta PX4 Storm is best suited for recreational target shooting, backyard plinking, and replica-style practice. One of its biggest advantages is flexibility: because it can shoot both pellets and steel BBs, owners can choose the ammo type that best matches the kind of shooting they want to do.
Is this a good CO2 pistol for beginners?
Yes. The PX4 Storm is a strong option for beginners who want something more realistic than a basic air pistol without jumping straight into a more specialized platform. It gives new shooters easy CO2 operation, repeater capacity, and the option to try both pellets and BBs in one pistol.
What ammo should I use in the Beretta PX4 Storm?
If you want economical, fast-paced shooting, many owners use Umarex steel BBs (https://www.umarexusa.com/umarex-1500-count-bb). If you want to experiment with the pistol’s dual-ammo flexibility, you can also use .177 pellets that fit the magazine properly. The big buyer takeaway is that this is not a single-ammo pistol, which makes it more versatile than many comparable CO2 replicas.
What accessories should I buy with the PX4 Storm?
The three most useful add-ons are extra CO2, steel BBs, and airgun oil. A practical starter setup is Umarex 12g CO2 cylinders (https://www.umarexusa.com/12g-co2-cylinders-12ct), Umarex steel BBs (https://www.umarexusa.com/umarex-1500-count-bb), and Chamber Lube with needle (https://www.umarexusa.com/rws-chamber-lube-pkg-with-needle). That combination covers power, ammo, and basic maintenance.
Does the PX4 Storm need oil or maintenance?
Yes. Like other CO2 air pistols, the PX4 Storm benefits from regular care. Umarex’s chamber lube is specifically described as a non-petroleum oil recommended by their gunsmiths and service techs for keeping the power plant operating smoothly, and it is useful on moving parts as well. Chamber Lube with needle (https://www.umarexusa.com/rws-chamber-lube-pkg-with-needle) is one of the most logical add-on products for this page.
Why would someone choose the PX4 Storm over another CO2 pistol?
The PX4 Storm stands out because it combines licensed Beretta styling, blowback action, and dual-ammo capability in one platform. A lot of competing CO2 pistols force the buyer to choose either BBs or pellets, while this one gives both options in the same pistol, which is a meaningful shopping advantage.
Is it worth buying the PX4 Storm with CO2, ammo, and maintenance supplies at the same time?
Yes. Buying the pistol with CO2, ammo, and chamber lube makes the product page more useful because it gives the customer everything needed to start shooting and maintain the pistol properly. It also reduces the most common post-purchase friction point: getting the gun but not having the right supplies ready
