Umarex Walther P99 GBB Blowback 380FPS CO2 Airsoft Gun

This powerful 380 FPS blowback airsoft pistol looks almost like the real Walther P99 pistol, but look very closely and you will notice one distinctive difference—the grip. The Umarex Walther P99’s grip is noticeably longer because that is where its CO2 canister is encased.

People with medium to large hands would obviously approve of this slight alteration, and it does provide a very nice ergonomic grip for most hand sizes.

The grip itself is made out of solid plastic material and feels comfy enough to hold. Also, not only is this gbb airsoft pistol looks like a near-clone of the real thing, even the weight is pretty close as well. Because of this, the Umarex Walther P99 offers a thoroughly pleasant balance similar to its real counterpart.


Metal was used to make the pistol’s slide as well as magazine, and with the CO2 canister thrown in, handling-wise, the Umarex Walther P99 is as reliable as they come. Now, the blowback is pretty impressive—definitely packs a good wallop. It is one the few CO2 blowback airsoft pistols at this price point that offers near realistic blowback kick.


This is actually a good pistol for beginners to practice basic aiming techniques and other pistol handling fundamentals. Just keep in mind that the shots are loud. In addition, when fired, the pistol’s slide tends to produce a metal clang sound effect that might just irritate you after a while—or perhaps, you might just end up appreciating the added realism!


As far as accuracy goes, well, if you are searching for a pistol that enables you to fire with precision beyond 120 feet, then the Umarex Walther P99 is not for you. Gbb airsoft pistols of this nature are typically excellent when it comes to short range shooting and if your aiming is decent enough, you can expect to accurately hit a target with this particular model from 105 feet or less.

Adding another plus point to this pistol is the fact that the CO2 consumption is amazingly low. On a single CO2 canister, it takes up to 300, maybe even 400 shots before a replacement is in order. Gas can be further conserved simply by racking the slide prior to pulling the trigger and firing the weapon.

Doing this actually disables the blowback feature. This is also a good option to have in case you are starting to feel annoyed with the pistol’s rather realistic blowback. So everything sounds good concerning this semi-automatic airsoft pistol. No disadvantages at all?

Well, the trigger pull is not the smoothest around. In fact, the trigger is actually pretty difficult to pull. The reason for this is because of the Umarex P99’s double action feature. This feature allows the trigger to cock the gun after each shot. As a result, it is no longer necessary on your part to pull back the slide in order to cock the gun.

So the tradeoff for this convenience is the trigger becomes a little heavier to pull. Users with decent grip strength should be able to handle the heavy trigger with minimal fuss. On the other hand, those with weak grip strength might not be able to shoot the pistol as fast.

Another problem is the pistol’s paint which is prone to scratches. It is merely cosmetic, but it does take away from the stylish appearance of this well-constructed airsoft pistol.


The Umarex P99 won’t win any CO2 airsoft pistol awards, but if you ever wanted to get a wallet-friendly priced Gbb pistol that is pretty darned powerful, accurate, sturdy, and comes with a realistic blowback feature, then this model definitely warrants a purchase.
