Or, don't drop your firearm .Wow, that sucks. And don't worry about people here chewing you up for a mistake, e-thugs tend to do that just to make themselves feel better. Good thing that the firearm didn't discharge. Might wanna start exploring striker fire type of firearm.
Hammers suck when you drop them on your toes, but I also try to avoid that .
You would have to be pretty unlucky to drop a 1911 and have it go off unless you had a firing pin spring well past needing replacement - that said - the same thing could happen with any floating pin design without a block safety (say, your AR15 dropped on it's barrel hard enough).
If you want a 1911 that is considered 'drop safe' you'd want a series80 and not a series70 I imagine. I'm a purist, I prefer to just keep my firing pin spring well maintained.
