Glock’s Fourth Act – the G19X

By Dennis Adler

The 2019 Umarex Glock 19X is the fourth Glock CO2 model and does a good job on its own of giving the blowback action Glock air pistol a really custom look with its re-contoured Gen5 slide and frame and distinct coyote tan finish.

You’ve heard the expression, “throwing in a ringer” well, this is what Umarex and Glock have done with the G19X. It’s an odd one too, because just like the Third Gen Glock 17 introduced late last year, the 2019 G19X is also not a field strippable gun. Because of that you might have expected it to be the gun that followed the Third Gen G17, but instead it came close on the heels of the first new model for 2019, the improved Umarex Glock 17 Gen4, which is the first Glock CO2 model that can be field stripped. I know I was surprised by this when I got an early G19X test gun from Umarex and it was not able to be field stripped.

The G19X is not so much a compromise between the Third Gen Glock 17 and Gen4 CO2 models, but rather a means to offer a newer design based on Glock’s 9mm G19X, a gun that is a bit of a ringer itself in the Glock lineup. Just look at it. It’s the first factory built gun with a custom finish and it is a Gen5 design.

The most significant differences between the Glock 19X CO2 model and the Gen4 Glock 17 blowback action, aside from the Gen4 being field strippable, is the trigger designs and the sights. The Gen4 trigger is identical to a Glock centerfire pistol in that it is a SAO. If the gun has been fired and a fresh round not chambered a Glock trigger will tell you at a glance the gun is not ready to fire because the trigger is resting further back in the triggerguard as shown. Rack the slide, chamber a round and the trigger moves forward and looks similar to the G19X trigger. The G19X uses a DA/SA trigger, which Glock’s don’t have. You can pull the trigger on an empty G19X and the gun will work over and over. You can’t do that on the Gen4. You also have a much heavier trigger pull with the G19X, but it is also very consistent and does not have an adverse affect on shooting accuracy. It’s wrong but it works well, just like it does on the Third Gen G17 CO2 model.

The 9mm G19X slide is finished with an improved nPVD (physical vapor deposition) coating to prevent corrosion finished in coyote tan color. The polymer frame is colored in a matching coyote tan shade, as is the nPVD finish on the 9mm magazines. Those same eye catching coyote tan tones from the centerfire model are duplicated on the CO2 pistol, along with the Gen5’s distinctive frame and grip contour and white dot sights instead of Glock’s traditional white outline rear and dot front. But that’s not what makes it a ringer in this competition for Replica Air Pistol of the Year. It’s the gun’s uncompromising velocity and accuracy. Field stripping is great, but sending steel BBs downrange at 376 to 380 fps average from a blowback action pistol beats taking a gun apart for fun. You really don’t have to fieldstrip a CO2 pistol to clean it; it’s just a great bonus feature that adds to the learning experience as a centerfire proxy. From a shooting perspective, I think velocity and accuracy, not to mention being accurate out to 10 yards at that high a velocity, greatly outweigh field stripping. Honestly, it has taken me awhile to come around to this way of thinking because I felt (and mostly still do) that a CO2 model that fieldstrips is as close as you can get to the real deal. With the G19X, however, this is something I can live with. I’ve got a lot of blowback action pistols that fieldstrip but none of them shoot at over 375 fps!

The G19X firing system is the same as the Third Gen CO2 model which means the magazine locks inline with the air nozzle. This helps the G19X achieve high velocities than the design used for the Gen4 model (which is the same used in the majority of blowback action CO2 pistols) and limits velocity to around 300 to 320 fps. The bad part is that the system used for the Third Gen and G19X does not allow the gun to be field stripped, nor does it allow the slide to lock back fully to the rear, as shown on the Gen4 model. Also note the fixed barrel on the G19X has a slight flair at the muzzle not seen on the Gen4.

We know that the firing system for the G19X is the same as the Third Gen G17 and uses what I call a short, short-blowback action design, meaning that while the slide travels back almost the full length of a centerfire gun when it discharges, it comes up short when the slide locks back or is manually locked open. We also know that the barrel is not a short-recoil, locked-breech, tilting-barrel design; it is a fixed barrel, like a conventional cartridge-firing short-recoil blowback action pistol and there is nothing wrong with this; it is just not how a centerfire Glock 17 is designed, but it works just fine for the CO2 model. Umarex certainly improved on this with the Gen4, but at the cost of the higher velocity achieved by the Third Gen G17 and G19X.

The other big difference is in how well the white dot sights are regulated to POA accuracy on the G19X. The Gen4 needs some POA POI aiming corrections, while the G19X is pretty much point and shoot using a traditional 6 o’clock hold. Some consider the use of white dot sights on the centerfire and CO2 models of the G19X an improvement over the traditional white outline rear white dot front sights used on other Glock centerfire and CO2 models.

The trigger for the G19X is also based on the Third Gen CO2 design, and that is a heavier trigger pull than the Gen4 Umarex model, which is almost exactly like a centerfire pistol at 5 pounds, 5 ounces. It is also a more precise trigger with a shorter take up and reset than the G19X, which averages 7 pounds, 2.5 ounces. But there is more than just a pound and change difference in the pull. The trigger on the Gen4 is an SAO, it is lighter because unless the slide has been cycled the trigger sits in the fired (rearmost) position and does not function. The trigger on the G19X is a non-Glock DA/SA that always rests in the forward, ready to fire position. In other words, if you load a magazine and do not rack the slide on the G19X and pull the trigger it works. Racking the slide on the G19X stages the trigger in a ready to fire condition, with a slightly lighter pull and less stacking than dead pulling a double action shot for the first round (which would never be the case with a centerfire Glock). But here’s the catch, even with the G19 trigger staged the length of pull remains the same as firing double action. Hands-on feel, however, tells another story. Let’s start with trigger take up on the G19X. Total travel is 0.93 inches. Of that, 0.75 inches is almost 2 pounds, 6.7 ounces average resistance, the balance of the pull weight is compressed into the last 0.187 inches and that is very a consistent pull that you can easily manage. Now, let’s compare that to the Gen4 trigger. Total length of take up is 0.25 inches plus another 0.125 inches to discharge. This is also a consistent trigger but with all of the resistance spread over the shorter pull. The Gen4 is smoother overall, but after the first 0.75 inches of take up the G19X feels almost the same as the Gen4. It’s not the right feel for a Glock but it is not a bad trigger by any means.

The G19X is the fourth Umarex Glock model in less than two years. The first model (far left) was a G19 Third Gen as a non-blowback with separate CO2 channel in the grip frame and a stick magazine. This was followed by a Glock 17 Third Gen design using a short, short-recoil blowback action and self-contained CO2 BB magazine. The Gen4 G17 with full blowback action, interchangeable backstraps and field strippable design came in 2019, followed by the Gen5 design Glock 19X in coyote tan. Not field strippable but of the latest Glock design and capable of exceptional performance, it’s become the most distinctive of the four.

The biggest advantages to the G19X is getting better than 50 fps more velocity from than the Gen4, sights that, in the general consensus, are easier to use than pre-Gen5 Glock sights, and since these sights cannot be changed like those on a centerfire Glock, you have a better fixed sight option with the G19X.

One other advantage to the G19X aside from very easy loading of BBs is a new seating screw wrench that makes it easier to turn down the cap and pierce the CO2 cartridge. This view also provides shows the warning info that is placed on the bottom of the triggerguard along with caliber markings and proof mark on the dustcover so all of the verbiage is discretely hidden and the rest of the gin looks authentic to the 9mm model. For the mandatory manual safety, the G19X uses a sliding lever in the opening where the serial number plate would go on a centerfire gun.

I had already found during the velocity tests that the gun’s POA needed to be 2-inches below the bullseye and windage almost dead center for POI accuracy. In other words, a proper 6 o’clock hold. If you can keep your aim with the white dot sights, which on this test gun were very well regulated, exactly in the same place and get into the rhythm of pulling through the trigger take up, pausing for a moment, and then breaking the shot, the G19X at 21 feet will pretty much hit in the same place. Since I am not always that consistent with holding my aim (but I am with the trigger pull) I managed a best 10 round group measuring 0.937 inches with seven hits in the bullseye all touching at 0.625 inches. A lot of blowback action models can shoot sub 1-inch inch groups at 21 feet but the G19X can do it more consistently. With everything thing else this blowback action model has going for it, from fit and finish to velocity and accuracy, there is a lot of appeal stacked in the G19X’s favor.

A darned accurate CO2 model that shoots to POA (6 o’clock hold) combined with a heavier but smooth operating DAO trigger system and three white dot sights delivers high velocity and impressive accuracy. Using a two-handed hold at 21 feet, I was two shots off of 10 in the bullseye. Total spread is 0.937 inches with seven hits in the bullseye all touching at 0.625 inches. Even if the G19X doesn’t win Replica Air Pistol of the Year, it is a winner by any other measure.

  1. I have the Gen 3 17 and did not consider the Gen 4 . Incompatible magazines with the Gen 3 and loss of velocity weren’t worth it to me. I understand that the ambi slide release on the rt side is non functional, if true I would deduct 5 points for being lazy by Umarex. It would have made more sense to offer something really innovative like a true model 19 or 26, still this is a pretty good pistol. Pistol of the year, nope

  2. Pistol of the year, hmmm… But the power plant’s description brought up an idea; This plant with no blowback in a long slide platform. I would love to buy an accurate “competition” Glock in the 500fps area. Adjustable rear sight and possibility for exchanging it to a dot…
    I am not sure if it would be better suited to the pellet firing model though.
