Trigger Pull: The trigger pull on the Umarex Glock 17 Gen 5 CO2 Blowback Pellet Pistol is what we would describe as closer to a DOA (Double Action Only) trigger. The blowback action does retract the internal hammer/striker which does relieve some of the trigger pull but the trigger is also used to rotate the belt magazine which gives the trigger a kind of friction feel especially right at the end of the pull where the rotation occurs. That said it is not a terrible trigger like some other belt fed Airguns but it is certainly nutlike a standard SAO type Glock trigger.

Accuracy: Starting with our power or velocity test we put 5 rounds through our Chronograph using lead pellets that where just over 7 gran. We were all using a brand new CO2 and the temperature being around 21 degrees Celsius or 70 degrees Fahrenheit, so not too hot or cold. Full disclaimer, we were having some feeding problems with the magazine at first but it did seem to sort itself out near the end of this review… All that said, we were able to get an average of 320 fps with our slowest shoot hitting 309 fps and our fastest shot hitting 327 fps, so pretty consistent overall. We then moved on to our accuracy portion of the Field Test for the Umarex Glock 17 Gen 5 CO2 Blowback Pellet Pistol Luckily the pellet feeding and trigger seemed to work better for me during this portion of the test but the trigger pull was very unpredictable being super hard with some shots and rather easy for others. This is not ideal for getting a good accuracy result, but we did the best we could and surprisingly got around a 3 inch grouping with a very uncooperative trigger. Our grouping did hit the target a little bit to the left but was well centered up and down.

Build Quality: The Umarex Glock 17 Gen 5 CO2 Blowback Pellet Pistol like most of the Umarex Glocks is very well made. We are thinking that Glock to allow Umarex to license Glock Pistols hammy have a quality control as part of this license agreement? Either way the Umarex Glock 17 Gen 5 CO2 Blowback Pellet Pistol is a solid and well built Airgun all around with quality material and very good fit and finish.

Realism: The Umarex Glock 17 Gen 5 CO2 Blowback Pellet Pistol in terms of realism as compared to a real steel Glock 19 Gen 5 for sure hits the mark in most categories. It is a bit lighter and you can not field strip it easily, there is also the not so much recessed barrel that is a bit of a giveaway but in terms of most other attributes the Umarex Glock 17 Gen 5 replicates a real Glock… Including the basic looks and feel, the metal slide and polymer frame, the full size drop out metal magazine, the blowback action and most of the working parts including the slide catch release, magazine release and trigger safety.

Pros:

• Good weight and feel to it, build quality and fit and finish seem very good.
• Really nice looking and full featured replica of the original Glock 17 Gen 5.
• Fully Glock licensed via Umarex.
• Easy to see white dot sights front and back.
• Working trigger safety.
• Accessory rail for adding a laser or tactical light.
• Full size drop out metal magazine that holds the CO2 and .177 caliber pellets.
• Nice high 21 round capacity.
• Slide spring feels nice and heavy provide a decent blowback recoil effect.
• Safety built into the serial number plate area keeps it well hidden.
• Can see through ejection port when magazine is out.
• Warning instruction are nice and discreet under trigger guard.
• 370 claimed fps is good for a CO2 blowback pellet pistol.

Cons:

• Barrel is not really all that recessed.
• No way to easily field strip it.
• Don’t like the clam shell packaging.
• Trigger is a bit on the heavy side.

Comments: We think many of us having been waiting for a pellet shooting version of the Glock from Umarex. We are a bit surprised they went with a belt fed version as belt fed magazines tend to be a bit on the heavy trigger pull side. Yes the Umarex Glock 17 Gen 5 CO2 Blowback Pellet Pistol has a stronger trigger pull as compared to a 4.5mm BB or 6mm Airsoft version of the same Umarex gun, as most of these Umarex based Glocks utilize a SAO trigger which is more comparable to a real steel Glock. On the plus side the Pellet version should be a bit more accurate, but we will see how this pans out when we do my comprehensive Field Test Shooting Video for the Umarex Glock 17 Gen 5 CO2 Blowback Pellet Pistol.
