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.
