Actually the side safety forces you to take your finger off the trigger to roll your hand over to release the safety with your right thumb..I have seen guns fire more than once due to the shooter having his finger on the trigger when pushing a tang safety forward. So to me it's a safer arrangement. It also works well for left handers...same thing, you need to use your index finger to push the safety forward so it can't be on the trigger at the same time.
