Things To Consider Before Buying A CO2 Airsoft Pistol

Here are some of the things that you can take note of before you purchase your very own CO2 Airsoft Pistol.

Durable Construction

Durability is always an issue when it comes to airsoft pistols. The natural wear and tear of these pistols are something that we cannot avoid. When you shoot with CO2 pistols, you can expect a heavier blowback.  CO2 guns typically shoot a lot more powerful compared to their green gas counterparts.

CO2 vs Green Gas

Which brings us to another question, what is better, CO2 or Green Gas? We would like to say either. Both green gas and Co2 have their own positives and negatives. Green gas can handle colder temperatures while green gas can’t. Green gas is much more affordable than using CO2 canisters. The list goes on and it will be a never-ending conversation between airsoft players and enthusiasts.

The Umarex Glock 17 Gen4 is just like the real thing. It is constructed of a polymer body and a metal slide complete with all the trademarks a real Glock would have. The grip of the Glock 17 from Elite Force features an anti-slip grip to easily hold this airsoft pistol. It also has a working slide lock that will only open when the gun is empty like when you use the real gun.

The difference that this has over the green gas version is that the slide of the CO2 version is more reinforced. There is a piece in the lining of the slide where you will see when placing them side to side, a part where the metal is thicker than the ones of green gas. This was made to withstand the pressure that the CO2 creates when firing it. This will make your pistol last longer.

Quick Glance

What's Good

  • Reinforced slide to match the power of CO2
  • Higher magazine capacity than most airsoft pistols
  • Classic Glock sights are amazing to use
  • Very accurate shooting

What's Bad

  • Magazine sticks out of the gun more
  • Doesn’t fit very well with holsters

Body and material

The Umarex 17 Gen4 is made with a polymer body and a metal slide like it’s the real deal. It also has all the trademarks the real Glock would have. It feels and looks like the real thing. It is built very well and additional reinforcements have been made to carry the gun through the shooting when using the CO2 magazine.


Like its green gas counterpart, this magazine can carry 23 BBs at a time. It can shoot at 330-350 FPS. Having a magazine with this high capacity means you can stay in the arena for much longer. No need to keep refilling every time.

Sights and Rails

Glock trademark sights are the best thing in the world for me. It allows you to clearly see your target with the white dot sights. These are best used under low to medium light. If you are the type to need flashlights or lasers in a match, don’t you worry because Umarex has got you covered. The Umarex Glock 17 Gen4 comes with an accessory rail that you can use to put all your favorite lights and lasers.

Our Wrap Up

Wrapping it up, the Umarex Glock 17 Gen4 can really be a powerful pistol if you know how to use it. Just like its green gas counterpart, it shoots very accurately. Looking on to your target won’t be a problem because the Glock sights are here to guide your shot. Attach a light or a laser if you need one. This CO2 version is one that we loved reviewing and is so exciting to see coming from one of the best brands in the country.
