I don't know anything about the safety of carrying your 1911 in Condition 2.
I do, from personal experience, know that it is incredibly unsafe to put your 1911 into Condition 2. There is no safe way to lower the hammer that ensures no discharge. The last time I ever put my 1911 into Condition 2, it went off. Fortunately two things prevented disaster. One, the gun was pointed downrange. Had I not been at a range, there would be no downrange, just whatever "ground" the barrel was directed toward during loading. Two, the round was a hang-fire, meaning that my thumb was clear of the hammer when the round went off, sending the slide rocketing back to where my thumb was moments prior.
I have never put my 1911 into Condition 2 since. I carry in Condition 1.
In sum, do not ever put your 1911 into Condition 2.
