Reality 101.
It's a GUN. It's NOT safe.
The 1911 in a cocked and locked condition must break two hammer hooks, .150 inch of the sear nose, and the half-cock notch...all at the same time...to fire a round. Additionally, the hammer must force the thumb safety past the spring-loaded plunger and out of engagement...and retain enough momentum to drive the spring-loaded inertial firing pin into the primer with sufficient force to fire it...which it probably won't on the first try unless several things are badly out-of-whack. In fact, I duplicated that very sequence and it took 37 repeated strikes
to fire an empty, primed case.
Statistically speaking, anything can happen...but in this case, the chances are
about as remote as being struck by lightning while crossing the Mojave Desert
at noon on your way to redeem your winning Powerball lottery ticket.
No...The Series 80 Colt and Series 2 Kimber passive firing pin safety systems don't make the gun any more safe in Condition One, unless you're crossing the Mojave Desert at noon to redeem your Powerball ticket...and a dark cloud rolls in from nowhere. Then you'd be advised to clear your pistol.
Those systems only make the gun more drop-safe...which isn't necessary unless the firing pin spring is badly worn and you are in the habit of pulling the gun while climbing an 8-foot ladder that's standing on concrete...and the gun must fall just about exactly straight down onto the muzzle.
The LDA is a marketing ploy that works on the psychological fear of a cocked pistol. It also appeals to certain law enforcement agencies that allow their people to carry anything that they want, but won't allow them to carry in Condition One.
It also indicates that Para Ordnance is assuming that nobody understands how the 1911 really works. The hammer is visible, therefore it gives rise to the "Ticking Bomb" mentality. When the hammer isn't visible...as in the case of a slide-action shotgun...nobody worries because they can't see the hammer. If they could, the reaction would be much the same.
The PO LDA system is a little too busy and fragile for my tastes in a defensive carry gun. Too much "Murphy Opportunity."
