Where can you buy one of those?.

Not sure they're made anymore    It's a Marushin Glock 21 to help you google it. 

There's just not much interest in picking up the 'brass' casings.  You could get a gas blowback that's just as real but doesn't eject anything to pick up later.  In combat training no one picks up spent brass (until training is over)  Just use biodegradable airsoft pellets and plink/train for cheap.  Don't get an electric or spring airsoft they're not realistic, propane is the best.  They make then with realistic weight and all metal.

Green gas is just propane w/ silicon added for a self lubing gun, they jack the price up so just use your own can of silicon spray lube and dry propane good to go

In my Leo training we had to pick up all the brass at the end of the day. But I can understand why others would not.

ya, it's too bad there's not much interest in it.   Drives up cost loosing the casings and more time loading them, but for training I think it would be excellent to add realism.
