Quite a few years ago, I bought a Springfield Armory 1911A1 built like the 45s we used in the Army. It has always been a reliable firearm and I did carry it for a while. I take it to the range once in a while, but no longer carry it.
As much as I love a mil-spec 1911, they were not drop safe. The odds of one going off when dropped may be low, but it is possible. When I bought it originally, I considered a firing pin block a do nothing part that could fail. I had one fail on one of my Colt pistols and did not trust firing pin blocks for a few years. Now, I consider them essential for a carry gun.
Some people change the firing pin with one that is much lighter and made of titanium. I do not know how much safer these are when dropped, but I expect they are not more dangerous.
Mil-spec 1911A1s feed 230 grain hardball very well; other ammo will need to be tested before trusting.
