I only carry condition one if I am returning from condition zero.
All my semi-auto firearms, rifles to pistols, are always carried:
Loaded mag
Empty chamber
Safety off
Yes it has its risks.
I run all of my semi-auto pistols as if they are SA only pistols, even though the only SA pistols I have are Browning Hi-Powers and a Browning 1911-A1 22.
My CZ 85B, S&W 659, and Walther PPK/S.
With the safeties in different locations, and different directions, I always carry like described above.
Hammer position with my carry:
The Browning's have very heavy recoil and hammer springs. Sometimes, I will cock the hammer on the BHP so that when it is time to rack the slide it is easier.
Only sometimes, as it is necessary to double check the chamber when handling a BHP with the hammer back.
If I am concerned about something, I will go to condition zero and then set the safety.
If I am threatened I will go to condition zero and the next thing will be a bang. I hope to never go there.
I have no fear irrational fear of condition one, but proper equipment and care must be taken, the safety switch can be actuated, so do not draw with finger on trigger, make sure holster covers trigger.
There is an online report of a man with a holster that was leather, and the holster covered about half of the trigger guard area. The leather softened with use and puckered inward, into the trigger guard. It eventually made its way in front of the trigger and shot the guy in the leg while seated in his car.
When I am in a vehicle my pistol may find itself in the center console, the map pocket of the door, in the glove box, etc. Depends on the vehicle.
If I take a pistol to condition zero, and then back to condition one, when I get to a safe place I drop the mag, remove the chambered round, put round back in mag, return slide, insert mag (BHP has mag disconnect), lower hammer and get it back to Condition three.
Since I do all the same, it doesn't take any thought on what I may be shooting with at the time.
Yes, I could not have both hands available, all kinds of things. Yes, if in a vehicle, going from Condition Three directly to Condition One could result in a stupidity discharge. I am not willing to "what if" myself into the nursing home.
So, I do not carry Condition One, unless it is coming from Condition Zero.
