I have to agree with American1776 about the drop-safe thing. Of course you are not supposed to ever drop your pistol... but things do happen.

In my .45 Commander I prefer a Titanium firing pin to a firing pin safety. Maybe I am wrong, but I base that preference on that first and foremost I want the gun to always fire.

In any case, as has been said already, the most important thing seems to be having knowledge of and confidence in your particular pistol, whatever age it is.
