I believe you may be confusing the type of safeties that block even intentional firings with safeties that try to block unintended firings (such as from drops or other mechanical stress). Pistols have multiple levels of safeties involved.

A trigger safety is meant to ensure that the trigger must be intentionally pulled (as opposed to moving during an impact) for the firing pin to be able to release and hit cartridge primer.

The 1911 famously has a grip safety, which needs to be depressed for the trigger to move. This is to try to ensure someone has to be gripping it with intent to fire, for it to be able to do so. While much safer than other pistols at the time, 100+ years later the design is relatively flawed, and isn’t truly drop safe, as the firing pin can still move.
