Watch Out For

mediumSome units may double-feed BBs initially and the slide may stick until worn in or lubricated; the CO2 screw may be too long, preventing grip extension from locking.

Compared To

vs Umarex Glock 17 Gen 5 MOS

Similar build but compact size; G19 MOS had a manufacturing defect with the CO2 screw interfering with grip extension, not present on G17.

User review of Umarex Glock 19 Gen 5 MOS on Reddit
I purchased the Gen 5 G19 MOS recently ... During the first 100ish shots, the gun occasionally double fed BB's into the chamber ... The slide was sticking a bit when returning ... the allen bolt used to secure the C02 powerlet is too long ... Overall I'd absolutely recommend this gun to anyone. A compact MOS speced 1/1 replica with full blowback is not only an awesome addition to your collection but it also doubles as a useful training tool in place of the real steel. 5/5 stars.

Umarex Glock 19 Gen 3 as favorite airgun
Umarex Glock 19 Gen 3 personally my favourite airgun. It's a solid replica, feels great in the hand, and the blowback is satisfying. Good for training and plinking.

Umarex Glock 17 Gen 5 .177 user asking about safety and accuracy
I have the Umarex Glock 17 Gen 5 .177 BB. It's fun to shoot but the magazine leaked CO2 out of the box. Accuracy is okay at close range but not great beyond 10 yards.

Discussion on Umarex Glocks quality and MOS feature
Umarex Glocks are solid, especially the MOS versions. The ability to mount a red dot makes a big difference for accuracy. Some models have better QC than others.

Glock G17 Gen 4 CO2 BB pistol discussion
The CO2 efficiency is pretty good on the G17, you can get about 3-4 mags per cartridge. The Gen 5 MOS adds the ability to mount optics which is a huge plus.
