Any reason one is preferred over the other? From what I understand 80 is theoretically safer while the 70 has a better trigger? That's what I got from a bit on Youtube, but didn't spend a lot of time there.
Theoretically is the key phrase. Technically yes- an original series 70 can fire when dropped…. Except it has to be at the exact angle, muzzle down, on concrete, from about shoulder height- exactly. The thing is, guns tend to rotate and fall where the weight is- the grip- first which will not fire an original series 70. In any case it is mitigated by a Ti firing pin and extra power firing pin spring. I am not aware of any legitimate 1911 being sold that doesn’t have those two items.
Even without them, it isn’t an actual issue. 1911’s have been used extremely heavily for more than 100 years and firing from being dropped is near unheard of. A series 70 with Ti firing pin and extra power firing pin spring firing from a drop in use is unheard of.
The P320 issue was that it fired when dropped a certain way on its butt or grip- muzzle up. Which is where pistols want to rotate and land on, and it’s muzzle up when it does so. Even if you could get a series 70 1911 to fire while dropped- it’s muzzle down on concrete- the only thing that is happening is some rock pepper- but it isn’t happening.
As for series 80, it adds a mechanical firing on block actuated by the trigger. A good smith can make an excellent trigger from a series 80.
