It all depends on what you train with. I still don't understand why that manual safety scares a lot of people, or the cocked hammer. I have much more reservations about carrying a DAO gun than a SAO w/ manual safety gun.
The majority of my training was with the 1911 platform. I instinctively click that safety off as I'm about to draw. If you're willing to take the time and practice clicking off the safety on the draw, it really isn't that bad. Even better is to shoot high thumb (thumb on manual safety) so the safety automatically clicks off as you draw.
I'm so used to a clicking a safety off that my first time shooting my SIG P226 in USPSA was a disaster. First stage, I drew and took a second to realize that I was shooting a different platform, with a *** look on my face. My thumb was depressing on the slidestop on my P226 waiting for a "safety" to click off.
Completely different platform, different action, different feel.
What I'm getting at is; if you're going to carry a 1911, train heavily on it and stick with one platform. Once you carry something else you're going hesitate when the time comes when you need to defend yourself.
As for the cocked hammer. It has a manual safety, and a grip safety. You have to grasp the gun with the safety off for the hammer to fall. It's not going to fall on it's own. Also, with a 1911 that works, the hammer should catch on the half cock notch if the hammer does ever fall (which it shouldn't ever).
Carry the gun around the house cocked and locked with an empty chamber for a while, you'll realize that Condition 1 carry is perfectly safe.
There's nothing wrong with carrying a 1911 coked and locked. It's a very capable platform, but it does take some practice to get used to it. Drawing and dryfiring is key here, or take a handgun course with your carry 1911.
Good luck
