By the looks of it, it is not a real gun.
At first look, the one thing that caught my attention is the frame. The slide looks like it came from a Beretta 92. In looking closely to the frame, it also looks like it had came from a Beretta 92. I then checked Beretta's website and compared the pics between what you had posted and a Beretta 92 FS and the slide and frame look identical.
Now you are probably wondering about the 1911 look that they have. If you look closely in the pic that you provided, there is a line that is close to the muzzle of the weapon about an inch or two towards the back of the gun. I would have to presume that this is were they attached the 1911 look of a slide onto the gun to fit the look that they want.
That is what I can see and I would be very surprised if this gun really did exist. But, I could be wrong too.
