Similar to the Dan Wesson Revolvers, this ASG CZ 75 Marushin Shell Ejecting Blowback Airsoft Pistol has loadable shells that you insert into the magazine along with the gas propellant. When the slide blows back it ejects the empty shell and loads a new shell ready to fire, just like a real gun! Much of this Airsoft gun is plastic but it makes up for this in the other areas of realism.
