Yes, you should confirm that the safety is ON before you even start the unloading procedure, but mistakes happen. Maybe you thought it was on when it wasn’t. Maybe a piece of your glove was in the slot and it didn’t click home all the way. No matter—you should never, ever depend on a manual safety anyway. With gloved hands, cold hands, wet hands, or even temperate hands on a sunny day, it’s all too easy to touch that trigger while wrapping a hand around to open the action.
