If an aircraft was designed with the same gotchas as a 9mm pistol, would any of us accept it?
Huh? What gotcha is that? If a 9mm pistol is loaded and you pull the trigger, it goes bang. If you don't want it to go bang, don't pull the trigger or unload it first. What is so hard about 1) removing magazine, 2) lock open the slide, 3) visually and manually check the chamber?
