KWC Desert Eagle .50 & Sigma SW40F Blowback Airsoft Pistol Review


Type: Airsoft Pistols.


Model:Desert Eagle .50 & Sigma SW40F.

Materials: Metal slide & polymer frame.

Weight: 2.5/1.8 pounds.

Barrel: Metalnon-rifled smooth bore.

Propulsion: 12 gram CO2.

Action: Blowback, single action only.

Ammunition Type: 6mm plastic Airsoft BB's.

Ammunition Capacity: 21/22 rounds.

FPS: 400/390.

Trigger Pull: The trigger pull for both KWC blowback single action pistols is very good, the Desert Eagle is a bit better with less play and a lighter pull while the Sigma SW40F still feels very good but has a little bit more take up and a slight bit more pull required.

Accuracy: I shot both guns from 20 feet out in semi rested position and got similar results. I was able to place 10 rounds in a 2.5 to 3 inch group and both guns shot well centered. I have full confidence that I could easily hit a man sized target from 50 feet away. Both KWC Airsoft pistols got right around 400 fps (5 shot average chrony testing) with the Desert Eagle only 10 fps higher than the Sigma SW40F and this was using .20 gram plastic Airsoft BB's.

Build Quality: The build quality for both guns is pretty much the same, both have a metal slide and barrel with a polymer frame and plastic grips, the Sigma SW40F had a plastic magazine release and trigger while the Desert Eagle used metal in these parts. The KWC Sigma SW40F seemed to wear a bit better as the painted finish seemed more durable. I found the metal on metal areas on the Desert Eagle where losing the paint and also in some of the high spots. Over all the guns worked very well and had good fit and finish.

Realism: The KWC Desert Eagle .50 and Sigma SW40F are very accurate replicas of their real steel counterparts, with the Desert Eagle also having the full licensing on it for added authenticity. The workings of both Airsoft guns are pretty much just like a real gun with full size drop out magazines and very heavy full blowback operation. The slides on each gun give a nice metallic sound when operating.

It's wonderful to get these KWC blowback Airsoft guns here in Canada finally and have the ability to review them for everyone. They remind me a lot of the Cybergun 4.5mm Steel BB blowback pistols very much and this is probably because there are Airsoft version of these guns also distributed by KWC. Whether you want one of these very nice Airsoft pistols for plinking and target practice or to use in battle on the Airsoft field, either gun would make a great choice. I am really loving the fact that I now have more guns I can review and Airsoft or 4.5mm Steel BB it really doesn't matter to me, I'm having way to much fun to care ;)
