How very Rube Golbergian...

To modern eyes, the Luger is such an extravagantly complex way to go about the task of launching 9mm projectiles. There are likely far, far more machining steps in the toggle subassembly alone than there are in an entire HK P30. For each Luger made, there were probably another one or two on the factory floor in the form of steel chips.

And imagine the design process... the sheer amount of model-making and trial-and-error... that this entailed before CAD and computer modeling was a thing?
