Trigger Pull: The trigger pull on the Umarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol is very similar to a real steel Glock Pistol as the full blowback action allows for a true single action only trigger and it has similar take-up, weight and release which makes this the perfect trainer if you own a similar Glock. Even the trigger safety is functional and not just for show.
Accuracy: Starting off with the Velocity portion the test, we 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 were the result of our 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 we shot 10 rounds into a fresh paper target 30 feet down range using a semi rested shooting position, so with our 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 we seemed pretty steady on this day, and for what we 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.
Build Quality: TheUmarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol being a licensed Glock Pistol means it has to conform to Glocks high standard so it is made very well with excellent fit and finish. Like there real steel version the slide is metal and the frame is a polymer, of course there are other metal components throughout like the magazine, inner and outer barrel, slide catch release and many of the internal parts.
Realism: The Umarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol absolutely looks the part of a Glock 19 MOS. When sitting on the table and even holding it in your hand, you are going to think it's the real deal until of course you drop the magazine and see that it is a CO2 mag. Mostly everything operates like a real Glock 19 MOS and because it is full blowback the slide cycles all the way back and forth and the slide spring is nice and heavy so there is no lag to it, it does not have the clanky metallic sound a lot of CO2 Blowback pistols have which adds even further to the realism. You can even fully feel strip this version just lie a real Glock 19 MOS.

Comments: We were excited when we first saw the Glock 17 and 19 Gen 5 MOS 4.5mm Steel BB Blowback Airguns at SHOT Show this year adn have been really looking forward to getting our hands on them. Essentially the Umarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol is built very much like an Airsoft Full Blowback Airgun but it just shoots 4.5mm Steel BB’s rather than 6mm Airsoft BB’s which some people prefer if you are not so much into Airsoft games. Along with being full blowback the MOS system allows for adding a red dot to the rear of the slide so this gives you even more option when adding accessories to the Umarex Glock 19 Gen 5 MOS CO2 Blowback BB Pistol. We were pretty sure this one is going to be our favorite Umarex Glock but we will know for sure after we Field Test it!

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!
