If the gun is a series 80 it has a firing pin block and has multiple safeties to prevent a round from discharging without a intent. It has the manual safety, it has the grip safety, and it has a firing pin safety. There are few pistols safer to carry cocked and locked or even with a hammer down on a live round in the chamber as a series 80 pistol. Even if the grip safety and manual safety broke, the firing pin safety will prevent forward movement of the firing pin without a pull of the trigger.
