Trigger Pull: The blowback action pre-cocks the internal hammer for a light single-action type trigger pull. I call it a a double-action trigger mainly because there is an indexing of a BB from the magazine into the breach area every time you pull the trigger, which means the take up is long and there is a little bit of friction from the mechanism that indexes a BB.

Accuracy: Using my Caldwell Ballistic Precision Chronograph, I was able to get really close to the factory claimed FPS of 365 with an average of 363 FPS. Shooting conditions were decent, a lot warmer than outside but still not as warm as your typical summer day. The temperature was 15 Degrees Celsius (59 Degrees Fahrenheit). In warmer conditions I am sure I would have hit the claimed 365 or even higher. I placed 10 shots into a paper target from 30 feet down range using my standard seated and rested shooting position. I was able to get just under a 2 inch 10 shot group, not bad at all! The pistol did shoot a little bit to the left which is common with most CO2 action airguns and I know it’s not entirely me since others have commented the same. Elevation was pretty close at 30 feet.

Build Quality: The Umarex Glock 17 3rd Gen Blowback BB Pistol seems well-made overall. Fit and finish are nice and slide wiggle is minimal. There is a bit of a clanky sound when the slide cycles but since most of these types of airguns are made out of pot metal with high zinc alloy content this is expected.

Realism: It absolutely looks the part of a Glock 17 3rd Generation. Sitting on the table and even holding it in your hand you are going to think it's the real deal until you drop the magazine and see that it is a CO2 mag. Mostly everything operates like a real Glock 17 but the slide is not a full blowback, meaning it only goes back about 3/4 as much as a true Glock slide would. One other noticeable difference is the ability to quickly field strip the pistol. You will need to remove a pin since the take down tabs are non-functioning and molded into the frame.


  • 1:1 scale replica of the Glock G17 9mm handgun
  • Metal slide with crisp blowback action
  • Polymer body with Gen 3 textured grip
  • Equipped with trigger safety and latch safety
  • Safety built into the serial number plate area keeps it well hidden
  • Tactical accessory rail under barrel
  • Full sized drop free metal magazine
  • Decent 365 FPS for a blowback BB gun


  • Slide sound is a bit clanky
  • Sights are not adjustable
  • Blowback action eats through CO2 faster
  • Would have liked to have seen more pristine packaging from Glock

Comments: This is the Glock airgun replica you've been waiting for. The Umarex Glock 17 BB Pistol is identical to the real steel version in almost every way. The dimensions are so accurate it will fit an official GLOCK Duty Holster. The Gen 3 model features an ergnomoic grip with a textured backstrap and finger grooves. With snappy CO2 blowback action, it feels and fires just like the real thing.

Love it

Im in love with this gun! The overall feel is amazing and similar to the real glock! It’s accurate when your co2 tank is full to half then it starts to drop but thats normal. An overall amazing gun and I hope to buy another soon :)
