I have had several different 1911's over the last 30 years and at now. I don't have ccw permit and unlikely that I ever will. My input is just from using at the range and drawing/firing that first shot, over and over.
I agree with the other members about cocked and locked as the way to go in your situation. empty chamber is just goofy, unless you are going to draw and scare somebody by racking the slide to load a round, only works in the movies
you did not say what 1911, maybe you did, but I do find a factor in whether you have factory thumb safety, or extended/ambi.
over the years, i found some extended / ambi safety too easy to bring down, and if yours is the case, i would have a gunsmith check it over, and get it to a positive click up or down, with right degree of effort. lots of safety features built in, but i don't like a loose safety in an open top holster
i have accepted that most holsters are open top kydex now, but i think for ccw, best way to go is a good leather holster IWB prefered with a thumb break which goes over your cocked and locked. that piece of leather over the cocked and locked is of extra comfort to me.
another option is the shoulder holster, cocked and locked, which covers all switches, but leaves the butt out to grab. if you go this way, don't wear suspenders, even the fashion ones, and no shirts with pockets to get in the way or have your hand or thumb snag up in a draw. i like the spring wire shoulder holsters, but hard to put gun back in. you might like the horizontal holster like the galco miami model which has thumbbreak
congrats on your ccw permit in the states, there is obviously a reason for the govenment to grant such where you are going, it this is justified then so is condition one carry.
so just as important as the gun you will carry, is what you carry it in, and how you dress for the part. lots of good advice from massad ayoob for your further reading and research. regards
