It isn't that simple. Most handguns actually have lots of "safeties" meant to ensure that it only goes off when held/pointed and the trigger is pulled. Triggers are also not like controller buttons. They generally require significant force to actually pull. No modern handgun should fire if shaken or dropped. Even guns from 100+ year ago (Colt 1911) have redundant safety features to protect against mishandling.

The 1911A1 is a marvel of engineering and anyone remotely interested in technology at all should study the design and its implications.
