Best Umarex CO2 Pistols
1.Umarex 9XP .177 Caliber BB Gun Air Pistol, 9XP Air Pistol, Black
The Umarex 9XP .177 Caliber BB Gun Air Pistol, 9XP Air Pistol, Blacklands squarely between realistic handling and everyday fun. At first glance it feels like a true-service sidearm: a metal slide that cycles with realistic blowback action, a comfortable ergonomics package, and a generous 20-shot .177 BB magazine that keeps you on target longer between reloads. Umarex built this with training and backyard plinking in mind — it presents like a proper replica but is tuned for approachable, reliable shooting.
The blowback system is the standout feature and deserves a closer look. Each shot cycles the metal slide with audible, tactile feedback that mimics the rhythm of a firearm; that sensation improves follow-through and makes each shot feel satisfying. Because blowback uses CO₂ pressure to operate the slide, the pistol delivers a noticeably punchy, realistic recoil impulse for an airgun in this price/size class. That realism makes it a useful option for basic firearms handling drills, dry-fire cadence practice, or just plain enjoyment for collectors who want something that behaves like the original.
Power and consistency are solid for the class. Running on a single 12-gram CO₂ cartridge (not included), the pistol launches .177 steel BBs at up to about 400 fps — enough for accurate short-range target work and lively plinking. Umarex specifically recommends using their branded CO₂ for the best seal and consistent performance; that’s practical advice because a good seal keeps shot-to-shot power steadier and reduces the risk of leaks. Expect dependable performance on mild temperature days; as with all CO₂ guns, extreme cold or heat will affect velocity and shot count.
Practicality was clearly considered in the design. The frame includes an integrated Weaver rail so you can add a laser, light, or small optic easily — a useful touch for anyone who wants to customize the pistol for training or low-light backyard use. Sights are fixed front and rear (which keeps the build simple and rugged), and a manual safety gives an extra layer of handling confidence for new shooters. The metal slide and the 20-round magazine both contribute to an authentic weight and balance that many buyers appreciate.

Factor to Consider when Choosing Best Umarex CO2 Pistols
1. Power Source and CO₂ Efficiency
All Umarex CO₂ pistols operate on 12-gram CO₂ cartridges, but not all models use gas equally. Blowback pistols deliver realistic recoil but consume more CO₂ per shot, reducing the total number of shots per cartridge. Non-blowback models are more efficient, offering higher shot counts and slightly greater velocity. Consider how often you’ll shoot — if you prioritize realism, go for blowback; if you prefer long sessions with minimal refills, a non-blowback design is more practical. Always use Umarex-brand CO₂ for a proper seal and reliable performance.
2. Velocity and Shooting Performance
The velocity, measured in feet per second (fps), determines how fast your BBs or pellets travel. Most Umarex CO₂ pistols shoot between 320 and 410 fps, depending on model and design. Higher velocities improve accuracy and penetration for target shooting, while lower velocities are ideal for safe indoor or close-range practice. Keep in mind that blowback action slightly reduces fps but enhances realism — choose based on your intended use.
3. Construction and Build Quality
Durability is key for both training and recreational use. Full-metal frames and slides offer better weight, balance, and longevity, giving a realistic feel similar to real firearms. Polymer-framed models, however, are lighter and more comfortable for extended shooting sessions. Umarex is known for its precise build quality, but choosing a pistol with a solid frame and reliable internals ensures years of smooth operation.
4. Realism and Blowback Action
If you’re training for firearm handling or just enjoy authentic shooting experiences, realistic blowback action is a must-have feature. The slide moves with each shot, simulating recoil and creating a lifelike trigger response. This realism helps improve grip discipline and sight reacquisition, making it a valuable training tool. However, remember that blowback uses more CO₂ — so if efficiency is more important, consider a fixed-slide version instead.
5. Magazine Capacity and Reloading System
Magazine design can influence your shooting rhythm. Umarex offers CO₂ pistols with magazines ranging from 15 to 20 rounds. Drop-free magazines, released by a realistic lever, add to the firearm-like experience and allow faster reloads. If you plan to shoot for extended periods, check whether the model supports spare magazines (e.g., part numbers like #2252519 or #2262024), as having extras can keep your shooting uninterrupted.
6. Accuracy and Sight Design
For accurate shooting, sight configuration matters. Many Umarex pistols feature fixed front and adjustable rear sights, allowing users to fine-tune aim for different distances. Some models include Glock-style or fiber-optic sights for faster target acquisition. If you plan to mount optics or lasers, look for models with integrated Weaver or Picatinny rails for easy accessory attachment. The right sight setup greatly enhances both accuracy and enjoyment.
7. Intended Use (Training, Plinking, or Airsoft)
Before buying, consider your main purpose. For training or firearm handling practice, choose realistic blowback pistols with metal slides and true-to-scale dimensions. For backyard plinking, non-blowback models with higher fps and better CO₂ efficiency are ideal. If you prefer airsoft gameplay, look for 6mm BB-compatible versions with hop-up systems that improve range and accuracy. Understanding your intended use ensures you get the right balance of realism, performance, and economy.
8. Accessories and Customization Options
A versatile CO₂ pistol allows easy upgrades and customization. Many Umarex models include integrated Picatinny or Weaver rails, letting you attach lasers, tactical lights, or small red-dot optics for enhanced functionality. Some models even support compatible holsters and spare magazines. Accessory compatibility not only improves performance but also helps tailor your pistol to your specific shooting needs, making it both functional and personal.
Frequent Asked Question Best Umarex CO2 Pistols
1. How many shots can I expect from one CO₂ cartridge?
The number of shots you’ll get from a single 12-gram CO₂ cartridge varies significantly depending on the specific model and how it’s used. Blowback models consume more CO₂ per shot (because the slide cycle uses gas) and may deliver fewer shots—sometimes 40–60 rounds per cartridge under ideal conditions. Non-blowback models may stretch to 70–90 shots or more in the same conditions. Temperature also plays a big role: cooler weather reduces pressure, which can drop both velocity and shot count. Using the recommended brand of CO₂ (Umarex) helps maintain a consistent seal and better performance.
2. Should I choose a blowback or non-blowback CO₂ pistol?
It depends on your priorities:
-
If realism, recoil feel, slide cycling, and training carry-over are your goals — then a blowback model is the better choice. You’ll get a more firearm-like experience (which is great for dry-fire drills, handling practice, or realistic plinking).
-
If you’re more focused on maximum shot count, efficiency, and simply having fun with targets or backyard plinking — then a non-blowback model will serve you well. You’ll get more shots per CO₂ cartridge and simpler mechanics.
Ultimately, weigh how much you value realism vs. efficiency.
3. What caliber and ammo type should I use with my Umarex CO₂ pistol?
Most Umarex CO₂ pistols for target/backyard use are in .177 caliber, which works with steel BBs or sometimes pellets. Models that are built for airsoft may use 6 mm plastic BBs. Use exactly the round type the model is designed for—mismatching ammo can damage the internals or reduce accuracy. For best performance:
-
Use high-quality steel BBs (if the gun is .177 steel-BB type).
-
Use officially licensed or recommended CO₂ cartridges.
-
Avoid mixing cheap/irregular ammo or over-sized loaders.
This ensures safe, accurate, and reliable shooting.
conclusion
When selecting a high-quality CO₂ pistol, it’s important to balance performance, realism, and reliability. A well-designed model should deliver consistent power, accurate shooting, and a satisfying shooting experience that mirrors real-firearm handling. Durability, ease of maintenance, and compatibility with accessories also enhance long-term value. Whether for training, target practice, or recreational plinking, investing in a trusted CO₂ pistol ensures dependable performance and lasting enjoyment every time you pull the trigger.
