LASur5r+P:
I'm comfortable carrying my M1911s cocked and locked. I'm also comfortable carrying my Kahrs or my Glocks.
"When I snick off that safety, I know that it really is a deadly force situation"
When I draw my M1911, as the gun passes through a 45 degree angle with the ground, I lower the safety. For me, the determination of a deadly force situation is when I draw the gun. If it isn't one, I don't draw. If I draw, the safety is lowered.
SpyGuy:
I agree that if one is carrying a Glock 17 with standard cap magazines, 1 round plus or minus is not an issue. With my 6+1 Kimber Compact, I sure do want that extra round.
I do not recommend carrying empty chamber. Yes, you can rack the slide quickly if you practice it. PROVIDED, of course, that you have 2 hands free to do so. My concern isn't that your support hand will become incapacitated. My concern is that your support hand will be busy doing something important, like pushing your wife to cover, picking up your small child, opening a door, or even fending off the perp. There are ways to rack the slide single handed, but they are neither fast nor particularly safe.
Regarding the idea that sometimes you would carry chamber empty and sometimes you would carry chamber full, I just shudder at that idea. Pick a way (condition 1, condition 2, or condition 3, if applicable to your gun), train that way ALWAYS, and carry that way ALWAYS. Because if TSHTF, you will fight the way you train. If you train to rack the slide as you draw, under pressure you will do that, whether the chamber is empty or full. And if you are now carrying cocked and locked, you'll likely be standing there trying to rack the slide on your 1911, and won't be able to because it is cocked and locked.
Kentucky Rifle:
I sure hope that your 1911s are series 80 and not series 70. The series 70 does not have a firing pin block. If you carry a series 70 hammer down on a full chamber, a sharp rap to the back of the hammer can cause a discharge.
Regarding your logic about why you carry hammer down (condition 2) rather than cocked and locked (condition 1), I'm afraid that I just don't understand your reasoning. You won't carry condition 1 because you think you might forget, under stress to lower the safety. If that's the case, why do you think you would remember to cock under stress? Or, to put it another way, if you think you can train yourself to manually cock the gun under stress, why do you think you can't train yourself to manually lower the safety under stess? Either way, hammer down or safety on, pulling the trigger won't do anything. So I don't see why you think condition 2 is more effective than condition 1. And with condition 2, you always have the possibility that you will slip and mess up while manually decocking, resulting in a discharge.
