IMO the firing pin is not resting "against" the primer,it is inside the bolt, and the spring that ejects it from the bolt is not under tension and still seems safer than a safty,we are after all human and forgetting is part of our make up as well as being naive. Look at park brakes, everyone has seen or done the classic jump out of the car and get back in and release the brake to find out it was not set to begin with. Just about every trucker I know has gotten out of their truck and back in and go to release the air brakes and realized they never pulled the button before they got out. Safeties can be the same way,think they are on and they are not. All I am saying is that no animal is worth any ones life and I do not take the chance. I live to hunt and my hunting would be over if I ever shot someone. Many a person is living with the guilt of doing just that(accidentally of course,intentionally is a whole different thing) and I do not want to be one of them.
Try this - remove the bolt from your rifle. Twist the back so that the bolt is uncocked (I'm assuming a cock on opening action). Look at the firing pin protruding through the firing pin hole. Press against it with your finger. Does it move back in to the hole? If not, then the firing pin is resting on the primer when you have a cartridge in the chamber and the bolt uncocked. That's MUCH worse than carrying hot with the safety on.
