It's an Israeli semi-auto magnum. Likely a 50. cal.
You may know to by the name of Desert Eagle.
My dad bought one a few years back, and trust me, it's not a revolver.
IT IS A FUCKING MAGAZINE LOADED DEATH MACINE OF HOLY PROPORTIONS!!!
Sorry for pulling you back to this old comment, but it must be said.
The DEagle has a gi-fucking-gantic magazine that goes into its grip. This gun's grip is unusually small for a gun size of its body, plus the blade is attached to the gun. If it was attached to the magazine, the whole contraption could become unstable because of the risk of damaging the magazine (or it's locking parts and other whatnot) when waving the blade around. More likely than not, this is a single-shot, or else it's a revolver with a sheath around it to make it more impressive. All in all, I think it would be much better to simply replace the gun with a Raging Bull .44 magnum.
