Trigger Pull: The trigger pull on the Umarex Glock 17 Gen 4 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 like the real steel versions.

Accuracy: At this point I have not shot either of the long barrel Umarex Glock 17 Gen 4 so I can only quote what Umarex is saying in terms of FPS which is around 410 using Green Gas or Propane. These longer barreled versions should shoot fairly hot compared to the much shorter barreled versions and since i do have a short barrel Glock 17 Gen 4 I may also compare it at the same time to see what the actual barrel length does in terms of fps velocity. Of course my Field test Shooting video will also focus on accuracy add see what can be accomplished shooting a 10 shot grouping at 30 feet down range.

Build Quality: The Umarex Glock 17 Gen 4 seems well made overall. It does seem a little bit underweight but still feels solid enough in the hand, Glocks are not known for being all that hefty. 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 Gen 4 look the part of these Glocks 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 them which makes getting to and adjusting the hop-up easy enough to do.

Pros:

Decent weight and feel to them, build quality seems good.
Really nice looking replicas of the original Glock 17 Gen 4.
Fully Glock licensed via Umarex.
Easy to see white dot sights front and back with rear sight adjustable for windage.
Recessed barrel for added realism when cut down.
Accessory rail for adding a laser or tactical light.
Full size drop out metal magazines that holds the Green Gas and 6mm Airsoft BB’s.
Warning instruction are nice and discreet under trigger guard.
Nice light SAO trigger as the blowback action pre-cocks the internal hammer/striker.
Working trigger safeties.
No red tips and more realistic outer barrel size.

Cons:

Only comes with the longer barrel so you need to either cut it down or replace it with a shorter barrel.
No way to put a mock suppressor on it to keep extended barrel.

Comments: 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’s great that we at least have a way to import these two Umarex Glock GBB Airsoft Pistols into Canada! Yes some home modifications may be required to cut down the inner barrel as the long extended barrels are certainly not practical for every day shooting. That said with the extended long barrels I did get out and shoot a few rounds through them and the added barrel length really does allow for a much faster velocity Airsoft BB making these Umarex GBB Airsoft Glocks more like snipper pistols.
