Hey everyone, Michael here with another field test video! Today, we are putting the Umarex Glock 17 Gen 5 CO2 Full Blowback BB Pistol through its paces in the indoor shooting range. If you're looking for the nitty-gritty details, specifications, and close-up angles, be sure to check out my dedicated Table Top video. For this session, we are strictly focused on performance: seeing how this realistic blowback replica handles when we actually put some rounds downrange. While this specific model does include the MOS plates for mounting a red dot, I decided to stick with the standard white-dot open iron sights for today's target testing.

Chronograph and Velocity Testing

Starting things off with the chrony test, I popped in a brand new CO2 cartridge to see what kind of speed we could get out of this Glock. Generally, with a heavy, fast-cycling blowback system like this one, I expect velocities to hover right around the 300 FPS mark. Let's see how the Gen 5 performed:

• Shot 1: 296 FPS

• Shot 2: 260 FPS

• Shot 3: 256 FPS

• Shot 4: 285 FPS

• Shot 5: 257 FPS

• Shot 6: 283 FPS

As you can see, the numbers jumped around a fair bit, and we stayed just shy of that 300 FPS threshold. This isn't super surprising, when you have a really stiff, snappy slide spring eating up that CO2 to cycle the blowback action, you're usually trading off a little bit of velocity and consistency to get that realistic recoil feel.

Accuracy Downrange at 30 Feet

Next up, I stepped back to my standard 30-foot mark to see what kind of grouping the Glock 17 could pull off on a fresh paper target. I did actually loaded 10 BBs for this string, which means the slide did lock back on the final shot since the magazine wasn't fully topped up to capacity.

Shooting the Umarex Glock 17 Gen 5 CO2 Full Blowback BB Pistol is an absolute blast. The trigger is fantastic, it has a failry light, short pull that perfectly replicates that classic Glock single-action feel. By holding my aim dead center, or maybe just a hair under the bullseye, the end result was a just over 2 inch grouping fairly well centered left to right, but a bit low on the bullseye. It's definitely more than accurate enough for practical, fast-paced action shooting.

Shooting Feel and MOS Features

The physical shooting experience is really where this Umarex replica shines. The slide action is incredibly crisp and fast, giving you a surprisingly snappy kick that feels highly authentic in the hand.

One huge bonus for this Gen 5 model is the Modular Optic System (MOS) design. Even though I rolled with the iron sights today, you have all the included plates needed to drop a micro red dot on top if that's your preference. Combining that optics readiness with a trigger that lets you rip off quick follow-up shots without pulling your muzzle off-target makes this an absolute joy to shoot.

Final Thoughts

Ultimately, the Umarex Glock 17 Gen 5 CO2 Full Blowback BB Pistol is a top-tier training option. If you own the real steel 9mm version, this 1:1 BB replica is a no-brainer for running speed reloads, practicing your draw, and doing target transitions in the comfort of your own garage or backyard. You're saving a ton of money on ammo while getting some highly effective muscle memory practice. It might not win any awards for sheer FPS or sniper-level target accuracy, but as a realistic action plinker and trainer, it absolutely hits the mark.

I finally got my hands on the new Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol that was introduced at this years SHOT Show, and I have already made my Table Top Review Video so make sure to watch that video for information on specifications, details, Pro’s and Con’s and more close up video… In this Field test Shooting video I focus on the performance of the Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol by testing the velocity out with my Chronograph, and I also shoot 10 rounds into a paper target setup 30 feet down range to see what the real world velocity and accuracy truly is.

Starting off with the Velocity portion the test, as always I use a brand new 12 gram CO2 along with standard 5.1 grain Steel BB’s. Temperature for the record was about 22 degrees Celsius or 72 degrees Fahrenheit. Here are the result of my multi shot Chronograph testing as it seemed to keep shooting faster and fast so I ended up using the last 5 shots for my average: 354, 349, 348, 343, 344 fps with an average of 348 fps. That was fairly close but just a bit under the 370 claimed fps. Warmer temperatures could for sure get this Blowback Airgun up to the slightly higher claimed fps.

Next I shot 10 rounds into a fresh paper target 30 feet down range using a semi-rested shooting position, with my hands resting on a sand bag up front, and sitting on a comfortable stool in the back, for somewhat stable shooting. There is always going to be a bit of human factor involved, but I seemed steady on this day, and I did get a nice result for a Blowback CO2 Air Pistol. The Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol shot good for me out of the box. The grouping spread out about 2 inches total well center up and down, just a hair above the bullseye but did wonder off to the left a little bit. Still a very good result for a blowback Airgun.

I was very pleased with the performance of the Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol. It had a lot more blowback action than I was expecting as the slide spring did feel kind of lazy to me when releasing it at first. The velocity was close to the mark and for sure as claimed in a warmer environment, and the accuracy was as good as you are going to get with a blowback BB Pistol. I didn't even mind the double action trigger at all as the first portion of the trigger is very light with almost no friction and even the release is not very heavy but for sure heavier than a true Single Action Trigger. I also like that you are going to get a lot more magazines worth of shots from a single CO2 out of the Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol with it’s semi blowback action and magazine design that seals off the BB into the breach area of the barrel. If you are OK with a DO trigger on a Glock, then I would suggest you chose the Glock 17 MOS Semi Blowback over the Glock 19 MOS Full Blowback simply for the higher fps, better CO2 efficiency and slightly improved accuracy.

I finally got my hands on the new Umarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol that was introduced this year at SHOT Show and I have already made my Table Top Review Video so make sure to watch that video for information on specifications, details, Pro’s and Con’s and more close up video… In this Field test Shooting video I focus on the performance of the Umarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol by testing the velocity out with my Chronograph and also shooting 10 rounds into a paper target setup 30 feet away to see what the real world velocity and accuracy actually is.

Starting off with the Velocity portion the test, I us a brand new 12 gram CO2 along with standard 5.1 grain Steel BB’s. Temperature for the record was about 22 degrees Celsius or 72 degrees Fahrenheit. Here were the result of my 5 shot Chronograph testing: 278, 275, 273, 273, 271 fps with an average of 274 fps. That was very consistent for a full blowback CO2 Airgun and close to the 280-290 claimed fps. Warmer temperatures could for sure get this Airgun up to the claimed fps.

Next I shot 10 rounds into a fresh paper target 30 feet down range using a semi rested shooting position, so with my hands resting on a sand bag up front and sitting on a stool in the back for somewhat stable shooting. There is always a bit of human factor involved but I seemed pretty steady on this day, and for what I consider to be a good result for a Full Blowback CO2 Air Pistol. The Umarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol shot a little bit low out of the box but well centered left to right. The grouping spread out about 3 inches total and that was mostly in the elevation so perhaps an inconsistency in velocity may have played a roll. In terms of windage (left to right placement), the group was closer to two inches total.

I was very pleased with the performance of the Umarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol , it shot really close to the claimed velocity with a fairly consistent fps for the most part. The accuracy was also right where I would expect a gun like this to perform and even though it shot a bit low on the bullseye, it was in the ball park and easy enough to simply adjust ones aim point to get more on target. The blowback action is quick and snappy with a nice simulated recoil and the single action trigger feels good. I did end up shooting two full 17 round magazines through this Airgun with no problem, and after letting it warm up a bit there is more than likely a third magazine left of CO2. If you want the most ultra realistic BB version of a Full Blowback Airgun with the ability to add a Red Dot to the top slide, then the Umarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol is the prefect choice!
