If you go airsoft, you can get full auto. I have a great G26 with a metal slide and barrel and it has the "happy fun switch" on the left rear of the slide (think G18). The slide actually recoils and these things are so realistic that serious trainers use them for force on force drills. The thing even takes down the same as my real G26 and the slide stop is fully functional. Removable magazine and it's the exact same dimensions and weight as a real G26. Fits my G26 holsters perfectly, too. Not the most powerful things in the world, but they are air/gas operated and pretty accurate.
