Trigger Pull: The trigger pull on the Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol is very similar in most ways to a real steel Glock Pistol with the blowback action, which does engage the striker alleviating some of the trigger pull to some degree. That said the trigger is more like a double action trigger in terms of weight and length, as the trigger pull is used to shuttle a BB into the breach, which does require additional trigger length and weight making it more like a double action trigger at the end of the day. The blowback action on this version is not full, but rather partial, so it does not go back as far as the real steel slide would go. The chambering of BB’s and the partial blowback design has an upside allowing for a higher velocity and more shots per CO2.

Accuracy: Starting off with the Velocity portion the test, as always 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 are the result of my multi shot Chronograph testing as it seemed to keep shooting faster and fast so we ended up using the last 5 shots for our 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 we 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 we 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.

Build Quality: Being Glock licensed via Umarex, the, Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol has to be made with Glocks high quality standards in mind. we are not 100% sure who actually makes this Airgun, as Umarex is not so much a manufacturer of Airguns, but more of a distribution and licensing company. We are pretty sure that KWC is making this Airgun for Umarex and KWC has for sure improved their quality over time in terms of fit and finish, so we are happy to say that the Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol is a really well built Airgun.

Realism: The Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol absolutely has most of everything you would want in a Replica Airgun, like blowback action, a working slide catch release, trigger safety, magazine release, and full size drop out metal magazine. Its shortcomings would be that you can not easily field strip its and it does have a trigger closer to a double action only rather than the Glock short and very light single action trigger. We can overlook this because it is very well priced and has a nice high velocity along with a lot of shots per CO2.

Pros:

• Good weight and feel to it, build quality seems excellent.
• Really nice looking and full featured replica of the original Glock 17 Gen 5 MOS.
• Fully Glock licensed via Umarex.
• Easy to see white dot sights front and back.
• Recessed barrel for added realism.
• Accessory rail under barrel for adding a laser or tactical light.
• MOS (Modular Optical System) on slide for adding a red dot.
• Safety built into serial number under the barrel.
• Full size drop out metal magazine that holds the CO2 and 18, 4.5mm steel BB’s.
• Slide spring is firm, will have a nice blowback recoil effect.
• Warning instruction is nice and discreet under the trigger guard.
• Not an overly heavy DOA feeling trigger as the blowback pre-cocks the internal hammer/striker but the trigger does move a BB into the breach area.
• Because of partial blowback action and magazine design, it has a higher fps and you get a lot more shots than a similar full blowback Airgun.
• Working trigger safety like the real steel version.

Cons:

• Trigger is more like a DOA trigger which is longer and heavier than a real steel Glock, but not bad.
• Sights are non-adjustable which is common with low cost airguns like this one.
• Blowback action is not full so not as heavy of a recoil feel as a full blowback Airgun.

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, and we have been really looking forward to getting my hands on both of them. They both look and feel just as good as they did at SHOT Show, and now all we need to do is test them out and see how they both perform in the Replica Airguns Indoor Sea Can Shooting Range. We know the Umarex Glock 17 Gen 5 MOS CO2 Blowback BB Pistol is for sure going to have a lot more power over the Umarex Glock 19, but the full blowback action of the Glock 19 Gen 5 MOS may take a win over power from the Glock 17 Gen 5 MOS. It may come down to which one is more accurate? We will have to wait and see so keep watching to find out who the winner is in my books.
