Umarex Glock CO2 Pistols

Published: 09/07/2020

Used worldwide by law enforcement and the military, the Glock pistol is one of the best selling handguns ever produced. Umarex faithfully reproduced these guns for the airgun market and we have a range of these guns to offer.


This is the grandfather of the Glock pistols, the model that came at the very start. The original fired 9 mm rounds, and the licensed replica, which shoots both 4.5 mm pellets and steel BBs with a muzzle energy of about three joules, promises a lot of fun.

The metal slide is visually impressive and gives the gun its remarkable weight. The blowback on some models makes every shot feel like the real thing, and with its rifled barrel, the Glock 17 delivers impressive precision.

In-store you can find both Gen 4 & 5 but what's the difference?

The most noticeable change on the Gen 5 can be found on the grip, the finger grooves which were first introduced on Gen 3 are missing. The front part of the slide and body have been tapered to make holstering a doddle, that's right the brick has curves. The sight is 3 dot rather than the U shape found on the 4th Gen and the 5th Generation is slightly lighter and shorter as evident in the specs below. A spring-loaded mag dropout mechanism has been included on Gen 5 whereas Gen 4 relies on gravity for removal.

Also, available in the Glock 17 range is the Dual Ammo. The dual-ammo model provides the ability to shoot both BB's and pellets as you would expect. A handy feature of this model is the magazine, which provides you with storage for 3 rotary clips plus 1. One clip for BB's and the other 3 for pellets. There is no lock open on the slider with this model though so you will have to keep count of your shots. Specs for the 3 versions below.
