The fact that there are accidental discharges with the Luger proves that no gun is idiot proof.

First, the Luger (at least from 1906 onward) has a very visible and tactile loaded chamber indicator. How someone can even think of trying to disassemble one without clearing the chamber is beyond me.

Second, it has a very effective safety that blocks the sear bar.

Third, in as issue condition it has a really heavy trigger with a long pull.

Fourth, although only valid for those with grip safety. The safety automatically engages whenever the pistol is not firmly gripped blocking the sear bar movement.
