No. You can’t have a slide and a revolving drum. It doesn’t make sense. You then have two different storing spots for ammo and since you can’t put cartridges in a revolving drum with a spring with current technology, it’s impossible to make.
From ehow -
“When the slide comes forward again, a small metal catchment catches a bullet from the magazine at the bottom of chamber and slides it forward into the breach of the gun’s barrel. Pulling the trigger lets the hammer drop forward, which strikes the firing ping. The firing pin in turn surges forward to strike the primer at the back of the cartridge. The gunpowder in the cartridge is ignited by the primer, which causes a huge expansion of gasses that force the bullet out the barrel of the gun”.
”...The gasses also cause the slide of the gun to slam backward. Another metal catchment on the slide snags the side of the cartridge that has fired and ejects the empty shell out the side of the gun via a small port. The slide also recocks the hammer of the gun. When the spring in the slide pushes it back forward, it catches another bullet and chambers it, allowing the firing process to repeat again and again. This procedure continues until the magazine of the gun is empty”.
“The revolver is opened first for loading. This may be done several ways. The goal is to expose the rear of the revolver’s cylinder, which contains many separate bullet chambers surrounding a central axis pin. One cartridge is inserted into the rear of each cylinder, typically six in all, and the cylinder is then locked back into place ahead of and above the handle.
The rear-striking hammer, which is at the back of the revolver, is raised. This is done by half pulling the trigger or cocking back the hammer with the thumb. This action turns the cylinder to align the back of the first cartridge with the barrel ahead of the cylinder and the firing pin behind the cylinder. When the trigger is pulled, the hammer falls forward, striking an internal metal aperture called a firing pin. This is a simple metal rod on a retention spring. The pin shoots forward and slams into the back of the primer of the bullet. The impact ignites the primer, which in turn ignites the powder within the brass shell. As the powder burns, it creates a huge amount of expanding gas, which forces the bullet from its seat at the top of the cartridge and propels it down the barrel of the gun”.
