Trigger Pull: The Umarex DS11 1911 NBB CO2 BB Pistol’s trigger feels exactly like you’d expect from a low-cost double-action-only CO2 pistol. The trigger does the heavy lifting. You’re pulling against a fairly stiff internal hammer spring (inside the barrel assembly) until it releases, snaps the hammer back, and opens the valve to fire. Run through the 18-round mag fast and your trigger finger will definitely notice.

Accuracy: II’ve already completed a full field test of the Umarex DS11, which is a bit out of my usual order, so I can share performance feedback now. On average it clocked 382 fps over five shots on my chronograph. From my standard paper target at 30 feet, a 10-shot group measured roughly 2 inches and was well centered, with several rounds landing in the bull’s-eye. You can watch the video here!

Build Quality: The Umarex DS11 1911 NBB CO2 BB Pistol is constructed almost entirely from plastic, keeping its weight just over a pound. While it lacks the heft of a full-metal replica, the lighter build makes it more forgiving if dropped on a hard surface. The fit and finish are solid, and its two-piece design secured mainly from the left side features very few moving parts or controls, which should contribute to excellent durability and reliability.

Realism: The Umarex DS11 is styled after the classic 1911 with a modern tactical look. It uses a double-action-only (DAO) trigger that’s relatively long and a bit heavy, not the short, feather-light feel of a true single-action 1911 trigger. The barrel is recessed and the CO2 is neatly hidden in the grips, so at a glance it could pass for the real thing. Up close, however, there are giveaways: a molded hammer, molded safety and slide-release, visible screws along the left side, and a seam where the two halves join.s.

Pros:

  • Low price well under $100 Canadian.

  • Shoots pretty decent, almost 400 fps and a nice 2 inch grouping fairly well centered out of the box.

  • Decent looking Replica of a modern 1911 Semi Auto Pistol. A lot more detail than most base non block CO2 BB Pistol.

  • Has a picatinny rail for adding accessories if you want to.

  • Double Action Trigger is pretty decent, Not going to be a super fast action shooter but it is manageable for a DAO trigger.

  • Uses the standard all metal stick magazine found inmost of these NBB CO2 BB Pistols.

  • I like the cut out in the slide showing off the gold inner barrel and ejection port.

  • Safety is not the typical on off style, more thought went into this one adn it looks better too.

  • Recessed barrel for added realism.

  • CO2 tab is fairly well hidden.

Cons:

  • Almost all plastic other than some internal metal parts like the barrel and spring and some other stuff I am sure.

  • DOA trigger a bit heavy but about the same as other similar Airguns like this one.

  • Sights are not adjustable and are all black with no white dots.

Comments:
The Umarex DS11 1911 NBB CO2 BB Pistol is a more thoughtfully designed and better-looking 4.5mm CO2 BB NBB Airgun than the typical budget options. It uses the common metal stick magazine, which is convenient since you more than likely have a bunch lying around and you can keep several preloaded and spend more time shooting and less time reloading on site. It also ships in a proper box, which adds to the premium feel. In my test at the Replica Airguns Indoor Shooting Range it performed very well.

Umarex DS11 1911 NBB CO2 BB Pistol Field Test Review

No Comments

I took the Umarex DS11 1911 NBB CO2 4.5mm BB Pistol out to the Replica Airguns Indoor Shooting Range today for some hands-on testing to see how it performs in real-world conditions. I haven’t filmed the full Table Top Review Video for this model just yet, but that’s coming soon. For this initial session, I wanted to focus strictly on performance, specifically testing velocity and accuracy. I ran a quick multi-shot chronograph session to get an average fps reading and followed that up with a 10-shot grouping test at 30 feet to get a practical sense of how accurate this pistol is right out of the box.

For the chronograph test, I used a fresh 12-gram CO2 cartridge and standard 4.5mm steel BBs. The room temperature was about 20°C. I noticed the velocity seemed to climb slightly as the CO2 settled in, so I averaged out the last five readings for consistency. Those shots came in at 386, 383, 377, 385, and 377 fps, giving an average of 382 fps. That’s very close to the manufacturer’s claimed 400 fps, and I’d expect it to reach or even exceed that number under warmer conditions. Overall, the DS11 delivered solid and consistent power for a non-blowback CO2 pistol.

Moving on to accuracy, I set up a target at 30 feet and fired from a semi-rested position, seated on a stool with my hands braced against a sandbag for stability. The Umarex DS11 1911 NBB CO2 4.5mm BB Pistol shot impressively well-centered right out of the box, which is a big plus since the sights are non-adjustable. My 10-shot group measured about 2.5 inches, with several rounds landing right in the bullseye. With a bit more trigger time and familiarity with the gun’s feel, I’m confident I could tighten that group even further.

All things considered, the Umarex DS11 1911 NBB CO₂ BB Pistol makes an excellent entry-level 4.5mm BB pistol for anyone looking for a tactical-style 1911 that’s affordable, reliable, and fun to shoot. Despite its simple, mostly polymer build, it looks great and feels comfortable in the hand. You can expect over 100 shots per CO₂2 cartridge, making it efficient and economical to shoot. Performance-wise, it’s got good power, accurate shooting right out of the box, and a straightforward design that should prove dependable over time.

In short, the Umarex DS11 1911 NBB is a great budget-friendly option that doesn’t sacrifice performance, and I have to say, it looks sharp for a basic, non-blowback BB shooter.

Replica Airguns August 2025 Mystery Box Video

No Comments

Yet another Mystery box with good stuff inside for me to discover and checkout and share with everyone! In this Replica Airguns August 2025 Mystery Box Video I reviewed three products from Umarex, and all of them are some sort of BB gun related product, one pistol, one revolver and one rifle and interestingly not all are CO2, as one is AEG powered which is more or less a new thing with steel BB guns. Barra introduced their 400e AEG AR Steel BB Rifle a while back and now Umarex has their own version of a similar AEG BB rifle in a sightly more true AR platform called the Umarex AER16.

The Umarex Marlin CO2 BB Revolver is really just a Marline licensed version of their Marshal CO2 BB Revolver but it us $50 less so unless you really want the Marshal licensing then go for the newer Marline version. Another Umarex product out of this months Mystery Box was the Umarex DS11 1911 NBB CO2 BB Pistol which is a pretty basic almost all plastic NBB CO2 BB Tactical 1911 that uses the standard metal BB Stick magazines. It does however look a lot better than most of these simple NBB Plastic BB Pistols on the market so in terms of looks it has that going for it for sure.
