Our Verdict:

GLOCK 19X GBB Blowback 6mm BB Pistol

GLOCK 19X GBB Blowback 6mm BB Pistol Airsoft Gun

The Umarex USA Glock 19X GBB is a green gas airsoft pistol with the same ergonomics and features as its real firearm counterpart. 

Not to mention…

It mimics the blowback action, the traditional sights, and the frame of the real Glock. Except for the finger grooves, that is. And it weighs about 1.45 lbs. Close enough to, if not the same weight as the real one.

That’s why it’s fully licensed by GLOCK. Its slide has complete rollmarks, and it has logos molded to the frame. Plus, even the British army uses it for their training.

But the realistic look and feel of this replica firearm isn’t the only reason we love it.

Also…

Even though it has a green gas magazine, you can fit a CO2 cartridge in it. It’s safe to do so, especially with the right CO2 adapter.

The Umarex airsoft pistol’s muzzle velocity is 300 fps. That’s within the standard. And given that the pistol is in good condition, its effective range would be from 40 to 60 feet.

However…

Because of the blowback slide, you’ll need more practice so you can hit the bullseye. It’s not as accurate as non-blowback airsoft pistols. But an experienced airsoft player won’t have trouble with it. 

And it’s a plus in authenticity. That’s why it’s highly sought after by trainers.

There’s more to it than that!

We’ve detailed out every score we gave this airsoft pistol for each metric. Read on to see why the Umarex 19X Glock GBB is the best gas-powered replica firearm for you.

Our Analysis, Comparisons & Test Results

Performance Comparison

GLOCK 19X GBB Blowback 6mm BB Pistol Airsoft Gun

1. Value for Money

Every feature of this airsoft pistol is highly satisfactory. It gave us more value than we expected. 

Of all green gas pistols that we’ve seen on the market, the authenticity and performance of this brand are exceptional.

And what’s even better…

… is that it’s relatively inexpensive! We’re not saying it’s the cheapest, but it falls right at the middle of the range of prices for which you can get airsoft pistols like this.

But you can get from it the same service that the more expensive products can. And its durability will last you ages. Add that to the fact that the green gas magazine is more pistol-friendly than CO2.

Plus…

Loading the magazine up is easy. That’s an important advantage while on the field. The other players will not wait for you to load up before they fire at you with their airguns.

For the price we paid, this Umarex airsoft Glock is more than satisfactory.

2. Power

We measure a gun’s power concerning its muzzle velocity and effective range. The full computation is a story for another day, so we’ll just give you a summary for now.

In essence…

Power is the energy released by the pistol over a given time. It’s commonly measured in watts. But in layman’s terms, we just say that power is how hard a BB hits after the pistols shoot it. 

Many factors affect that, like the weight and type of BB, the condition of the pistols, etc.

For this particular airsoft pistol, it fires a 6mm BB with up to 1.6 joules.

Take note:

The standard for airsoft pistols is 1.5 joules. They’re not too far apart, and 1.6 is the maximum figure. 

All of these just mean one thing for us – it’s a very powerful replica firearm. We’ve seen it by simply inspecting the stock. After firing it and feeling how the slide blew back, it didn’t disappoint us.

Hurting your opponents in the airsoft field is not the goal of the game. But this kind of power is advantageous so the BB can reach the pistol’s maximum effective range.

3. Versatility

If you check the label, this particular Umarex GBB is a green gas type. Meaning it has a magazine made for green gas or propane mixed with silicone oil. 

That’s important information because the two gas types are compressed under very different amounts of pressure. Whereas CO2 is stored in cartridges under 1200 psi, green gas is only pressurized to 300 psi. See the difference?

But still…

This faux Glock can withstand a 12g CO2 cartridge.

It didn’t get jammed up or break easily as if we were just using green gas. We suggest that you consult a professional when choosing a CO2 adapter for it, though. Safety has no price, right?

4. Range

After knowing the maximum power and the muzzle velocity, you can get a ballpark of how far a gun can shoot a BB. The Umarex Glock is known to propel ammo from 40 to 60 feet. 

That’s a great number for outdoor games, and even more so indoors.

That’s why…

We highly recommend this pistol. That range can be an advantage in the field. Whether you’re playing for fun or training.

5. Accuracy

In our reviews, we view accuracy in two ways. One means how well you can hit the bullseye. The other means how well the airsoft pistols mimic their firearm counterpart.

With this airsoft pistol…

We took a point off from its accuracy because you’ll find it hard to hit your target with this pistol. Thanks to the realistic blowback slide.

But it’s the authenticity that makes it highly sought after compared to other replica firearms. Just ask the British Army – they’d agree with us!

Frequently Asked Questions (FAQ’s)

2.What size of CO2 cartridges would fit its magazine?

A 12-g CO2 cartridge fits the magazine of this green gas airsoft pistol.

3.Can you put a suppressor on this gun?

You can’t put a suppressor on this gun because the barrel isn’t threaded.

4.Is the barrel threaded?
