i don't know how it is with real weapons, but with airsofts you have the problem that after a while this thing which fly away in the gif gets lose & then this what you see in the gif happens.. but normaly i would think that real weapons are made out of a hard material like metal..and there it "should" not happen.. i think.
The barrel is permanently affixed to the frame, and the spring slides over the barrel. You then set rhe slide atop the barrel, with the muzzle aligned with the port in the slide. From there, you have to rack the slide all the way back, like you're loading it, for the slide to lock back in place.
For this gif to happen, he would have to have failed to rack the slide all the way back. The spring would be under tension, but when he pulls the trigger nothing would hold the slide properly in place.
