I carry the same pistol as Savage, a P12-45, and I carry it the same way. Yes it made me a bit nervous when first doing so, but after becoming more and more familiar with it, I realized an accidental discharge will happen only if I do something stupid, like try to holser it with my finger on the trigger and the thumb safety off, AND gripping the backstrap to depress THAT safety.
I also notice a lot of people say, "You can draw and cock ALMOST as fast...", and that's the key word: ALMOST. Sorry, but that's not good enough in my book. We are carrying to defend agains lethal force, and that can mean ANYTHING. Criminals want, and will take, absolutely every opportunity they can to get an advatage. If you're not comfortable with cocked & locked, find a different weapon. You need every advantage you can possibly get, and that includes the fact thay you may only have one hand free.
Lastly, it's my understanding that the 1911 was originally designed with only ONE external safety; the military pushed to add the other. I've deliberately cocked and UNLOCKED my Para (unloaded, of course) and dropped it from as high as five feet on the floor several times, and it did not discharge. A properly maintained & unmodified 1911 should not be a problem carrying cocked & locked.
