Glock 17 Gen. 4 Reviews
Tell us what you think
Received 29 Nov. WOW! This is as close to the powder burner it represents as one can get. In the hand is feels exactly the same. The trigger is as good as the actual firearm. The magazine loads easy. The slide locks back on the last BB. The ammo used was Hornady black diamond BB's and Daisy Avanti precision ground BB's. Found no difference in performance. Five shot group at 15 feet was 2 inches or less and shoots a little left, acceptable in my opinion. If I had to keep only one of the MANY replica handguns I have and I like several of them, this would be the one. I'm at 1400+ rounds and zero problems.
Boost the FPS to around 450.
I purchased two extra mags (a bit more expensive than they should be) to extend practice time. I loaded the mag 3 times before the power falls a bit. You can get around 60 - 65 good shots from a CO2 cartridge. Experimented with the magazines and all of them held air for 5 days and still functioned properly. No leaks. Very happy about that as this doesn't happen all the time.
This air gun looks and feels great . The trigger pull is nice and light ,
Only about 3 out of 10 bbs correctly fired . Some of the failures just rolled down the barrel . Fixed sight , and at 3 yards it hits 8 Inches low and 3 inches left .
The gun is a very accurately made replica. Actual Glock accessories ( like lights , lasers , holsters etc ) fit on it for training.
However its poor accuracy and poor reliability make it a poor choice for shooting.

Verified BuyerWhat sets this apart from other CO2 handguns is the action. Cocking the slide back has such a niece feeling. The action feels and sounds solid, nice weight.

Verified BuyerDefinitely worth the money I paid I’ve had 2 before and the gen4 is definitely the way to go
Nothing I believe they nailed it with this one
It was a little stiff field striping it at first but eventually she softened up and im happy about that because I believe in cleaning and oiling my firearms
Has the feel of a legit Glock. Very realistic with the blowback. And I really like how easy it is to tear down for cleaning.
Nothing that I have any real concerns for. However I have had issues with Copperhead BB’s so I stick to the Umarex Hornady BB’s as they don’t jam in the barrel.
I would stick to the Umarex Hornady BB’s and stay away from the Copperheads. I have read that lead BB’s work great too but I haven’t been able to find any lead ones where I live.
The weight, the feel of the grip texturing, the fact that it can be field stripped. This looks like the real Glock, and I enjoyed shooting it.
The only thing I would change is the awful plastic packing that Umarex uses.
Suggest you get a second Magazine when you order the pistol.

Verified BuyerIn my opinion this is the best replica you can buy, everything works well, great finish, I love it
I wish this gun came packaged in a nice box and not in cheap plastic.
don't let this glock out of your collection
Great for dryfire type exercises (very Low cost shooting), Realisticish looks and takedown.
Upgrade options (ie. Barrels, trigger)
Allows me to target practice in my yard with a gun exactly like my real one. Cheaper ammo and no range fee. Lots of fun.
I wouldn't change a thing Umarex got this one perfect.
An extra mag is always a good idea.
Feels GREAT in the hand. Looks quite authentic. You can tell cate went into the engineering of this gun.
This is the LEAST ACCURATE airgun I own - and thats Saying something. Even for an airgun this thing is ridiculous. At twenty feet I was lucky to get a three inch shot group! As an example my Umarex Brodax which is half the price is unbelievably more accurate. The M&P 9 which is also less expensive is nearly a tack driver. This thing though, way too much money for way too little performance.
I liked everything about it except the hammer broke a month after I bought it
Stronger hammer
Go easy on the slide when u cock it

Great feel, weight, and look. I've really enjoyed it for plinking and feel.
Not much, it's a BB gun pistol. For the price point, pretty awesome!
