The pistol looks like a glock but the grip looks different? The bass on the ground looks like 38 special, rimmed case. ?
Unless the firearm has been "altered" in some way to customize it, I don't think it even really looks like a Glock. If it is a Glock, it is a "generation" that I'm not familiar with.
But then, I don't know enough about other handguns to be able to determine what brand it really is.
