After building Jack streat's Desert Eagle, I wondered if it was possible to use a similar mechanism in a smaller pistol, like a Glock. And so, here it is! The blowback works just like Streat's Desert Eagle, but I've made big modifications to the mechanism to fit it into a smaller space. Also, unlike Streat's Desert Eagle, it uses no modifyed pieces; just genuine Lego elements and rubber bands. For those who don't understand how the blowback works, I took some pictures of the internals that go step-by-step. Basically, as you pull the trigger the slide moves back about 3 studs and then slams back foward. Then, as you release the trigger back foward, the mechanism resets. The gun also features an open ejection port and a removable (and quite short) magazine. Hope you like it!
