Trigger Pull: The trigger pull on the Umarex Glock 17 Gen 4 CO2 Blowback BB Pistol is single action only so you will need to rack the slide first to not only chamber a 4.5mm Steel BB in the breach area but to also cock the internal striker. There is a working trigger safety on the Umarex Glock 17 Gen 4 CO2 Blowback BB Pistol and you’ll also find the Glock 17 Gen 4 has a nice short and light trigger as you would expect similar to the real steel Glock. Perfect for fast action shooting!

Accuracy: At this point I have not shot the Umarex Glock 17 Gen 4 CO2 Blowback BB Pistol so I can only quote what Umarex is saying in terms of FP2 which is 300. That sounds reasonable based on other Airguns like this that have that full blowback action since much of the CO2 gas is used to work the action of the slide. This not only reduces how many shots you can expect o get out of a single 12 gram CO2 cartridge but a reduction in power over non-blowback or even partial blowback CO2 Airguns.

Build Quality: The Umarex Glock 17 Gen 4 CO2 Blowback BB Pistol looks to be well made overall with metal and plastic parts where you would find them on a real steel Glock 17 Gen 4. Fit and finish are nice and the slide wiggle is next to zero. The slide spring is very heavy and the sound of the slide when racked and released does not have that cheap metallic sound some blowback Airguns have. I am expecting some pretty decent blowback action recoil from the Umarex Glock 17 Gen 4 CO2 Blowback BB Pistol when I do my Field Test Shooting Review!

Realism: The Umarex Glock 17 Gen 4 CO2 Blowback BB Pistol 100% looks the part of a Glock 17 4th Generation, 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 BB/CO2 mag. Mostly everything operates like a real Glock 17 including the slide catch release, trigger safety, magazine release and even the take down switches for quick field stripping and access to the adjustable hop-up, yes it is adjustable.

  • Good weight and feel to it, build quality seems very good.

  • Really nice looking and full featured replica of the original Glock 17 Gen 4.

  • Fully Glock licensed through Umarex.

  • Easy to see white dot sights front and back.

  • Recessed barrel for added realism.

  • Accessory rail for adding a laser or tactical light.

  • Full size drop out metal magazine that holds the CO2 and 18 4.5mm steel BB’s.

  • Slide spring feels heavier than most full blowback Airguns, should have a heavy blowback recoil effect.

  • Safety built into the serial number plate area keeps it well hidden.

  • Comes with additional Backstraps for different sized hands.

  • Warning instruction are nice and discreet under trigger guard.

  • Great feeling single action only trigger as the blowback pre-cocks the internal hammer/strike.

  • 300 fps is decent for a full blowback BB gun.
