I'm still not clear on your question and suspect that there's something else behind what you are asking. For example, are you asking this because you think cocked-and-locked is somehow more dangerous or requires more training than other means of carry?
First, I suggest that everyone who is going to carry get some training beforehand, particularly on drawing and holstering. Many (most?) NDs occur while holstering. And they can occur with any kind of gun. Here's a link to just such an accident that occurred with a Sig:

I've had training at LFI and SigArms Academy. That training was not specific to a 1911 and most of the other students were not carrying a 1911.
Does cocked-and-locked require "special" training above and beyond other types of guns? Well, when carrying condition 1, you need to remember to lower the safety on the draw stroke, but only after the barrel has passed through a 45 degree angle with the ground. Before reholstering, you have to remember to apply the safety.
With a DA auto, like a Sig, you don't have to lower the safety while drawing, but you do have to decock before holstering. With DA autos like S&W, Beretta, or HK, if you carry them on safe, then you still have to take them off safe while drawing.
DAO or striker-fired guns like the Glock simplify things since there is no manual safety or decocker.
Now, is condition 1 somehow less safe to carry than the other guns? Let's focus just on reholstering. Many NDs occur because the shooter leaves his finger on the trigger while reholstering. The holster stops the finger, the gun keeps going, and so the finger thus pulls the trigger. Boom!
With a 1911, if you remember to apply the safety before reholstering, then the gun won't go off if you leave your finger on the trigger. If you forget to apply the safety and leave your finger on the trigger while reholstering, it probably will discharge since you have a short, light trigger pull.
Let's compare this with a Sig. If you remember to decock the Sig and leave your finger on the trigger, then you may well have a discharge -- the only thing going for you is that you have a longer, heavier trigger pull. If you forget to decock your Sig and leave your finger on the trigger while reholstering, then you're in the same situation as with a 1911 -- you've got a short, light trigger pull. So how, exactly, are you safer?
With a Glock, if you leave your finger on the trigger while reholstering, you have a short, light trigger pull. You do have the option for stiffer trigger pulls that might give you a bit of help here.
Personally, I can't understand why some folks think condition 1 is more dangerous or requires more training than other guns. I think they just have an irrational fear of the cocked hammer.
