Physics 101 - conservation of energy. With no battery, all the energy needed to eject the shell and return the slide to its original position must come from the energy imparted by the trigger pull. Minus friction, coil conversion loss, and acoustic energy loss obviously. Duh.

Reverse engineering reveals the trigger pull must be substantial. Very substantial (aka dayum dude what's up with this trigger). So the word I'm looking for is impractable. Or impracticable ? Or something like that 😉

But very, very cool !
