It looks to me the p10c is fairly safe, with:
1. Trigger safety (part #16) blocking the trigger
2. Trigger bar (#7) raised when cocked.
these 2 aspects alone prevent firing pin (#3a) to go forward and hit the primer.
In an unlikely scenario when the above 2 conditions are somehow bypassed, the Automatic Safety (#3d) will either block the firing pin(#3a) completely, or slows it down before it hits the primer. I think this is the main purpose of the Automatic Safety. I don't think it's logical to lable the function of this part to be "unsafe" of "failed" when it does its job either fully blocking or just tripping

the trigger bar.
