Pretty harsh Armafix, rough day? Anyhoo, it was the steel firing pin in the Colt 70's that was of some concern and the reason for the birth of the 80's. The problem (which isn't one) is that it was either theorized or actually happened, that IF the pistol was chambered (safeties initiated or not, wouldn't matter) and dropped with force on its muzzle, the inertia enacted on the weight of the firing pin itself would (could) overcome the firing pin return spring and strike the primer...discharging the firearm.
Instead of the series 80, Colt could have (should have) {JMB is long gone at this point, so is his input. We have to rely on whatever knucklehead most likely working on Contract for Colt of the time} A: Understood that the only true safety IS in between ones ears, and a company can't engineer out stupid (It's a gawd damn gun for Krists sake!?)
B: Wait 2 decades for firing pins to be made from titanium (lighter weight=less inertia=the return spring able to hold back the pin.).
C: Understand that the "problem" isn't a problem in the first place if and whenever "A" is applied.
Some might be thinking of a stronger firing pin return spring with the steel firing pin as the most obvious fix, apparently this wasn't a fix. It slowed the pin down excessively under "normal" operations.
