Weight: 1.45 pounds (658 grams).
Barrel: 3.75 inches metal non-rifled.
Propulsion: Green Gas or Propane.

Trigger Pull: The trigger pull on the Umarex Glock 17 4th Gen GBB Airsoft Pistol is fairly short with only a little bit of take up, the release is light and crips. The blowback action resets the internal Hammer / Striker with each shot for that true single action trigger and it’s also nice that the trigger does have a working trigger safety.

Accuracy: At this point I have not shot the Umarex Glock 17 4th Gen GBB Airsoft Pistol so I can only quote what Umarex is saying in terms of FP2 which is around 300 using Green Ga or Propane. This is fine for playing Airsoft games but for Canada import it can get a bit sticky. Luckily we where able to get a bunch into Canada so hopefully we can get some more in our Canada Replica Airguns Store in the future… US supply will be less of a problem.

Build Quality: The Umarex Glock 17 4th Gen GBB Airsoft Pistol seems well made overall. It does seem a little bit underweight but still feels solid enough in the hand. The Slide is metal but has a bit of an unusual finish that makes it look a lot like the plastic frame rather than a more shiny metal look. All the parts seem to fit nicely, maybe even a bit snug at first as I noticed the side had a bit of friction to it but seems to be working in nicely now.

Realism: The Umarex Glock 17 4th Gen GBB Airsoft Pistol  looks the part of a Glock 17 4th Generation all day long. Other then the slightly lighter weight it would be hard to tell off hand until you remove the magazine and take a closer look. All the parts work as you would expect them to, similar to the real steel version and you can even fully field strip the Umarex Glock 17 4th Gen GBB Airsoft Pistol which makes getting to and adjusting the hop-up easy enough to do.

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

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

  • Fully Glock licensed.

  • 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 20 6mm Airsoft BB’s.

  • Warning instruction are nice and discreet under trigger guard

  • Nice light SAO trigger as the blowback pre-cocks the internal hammer/strike.

  • Working trigger safety.


  • May or may not come with an orange top but can be fairly remissly removed.

  • Sight are non-adjustable which is common with low cost airguns like this one.

  • FPS is a bit low making Canada import difficult.


Getting the Umarex BB versions of the Glock 17 and Glock 19 has for sure been a bit easier since fps velocity is not a factor. So it was great that we where able to import at least some of these Umarex Glock 17 4th Gen GBB Airsoft Pistols into Canada. I hope we will be able to continue supplying the Glock Airsoft versions in our Canada Replica Airguns Store but I can not promise anything… So if you see some in stock then grab one while you still can!
