Thanks. I thought so but wasn’t sure. Still a floating firing pin but it is deep in the frame and not easily struck. I don’t know if a drop straight on the end of the barrel on a hard surface could jar the pin forward enough to strike the primer if the pistol was cocked and locked. Seems unlikely.
If I recall correctly, it *can* do that in a muzzle drop scenario. This is one reason why people started suing Colt in the 1970s when the 1911 and other automatics became vastly more popular for concealed carry and 1911s started hitting the ground while loaded with cartridges possessing softer primers than what the military loads use.
Colt’s solution was the Series 80 with the firing pin block. Other makers later returned the Series 70 design to production but with a titanium firing pin (among other adaptations.) A titanium pin doesn’t mass enough to hit a commercial primer with sufficient force to detonate it in a drop.
GunMagWarehouse had a pretty good article about the differences: https://gunmagwarehouse.com/blog/1911-series-70-vs-series-80/
