Desert Eagle

I can tell that this is an airsoft version of the Desert Eagle due to the notch in the slide activating the slide catch to lock the slide back is a little bit further back than the real one. The reason this happens is because the slide of the airsoft gun can only go so far back before it can be converted to a real gun by swapping parts out with real ones. They prevent this by making it so if you try to convert it to a real gun, the gun will break on the first shot because of how fast the slide goes back in such a short distance, causing it fly backwards and hit the user right in da face to teach him a lesson on what he tried to accomplish.
