Ok here's my options in carrying as I see them. I can carry with
1) one in the chamber, safety off, hammer down.
2) one in the chamber, safety off, hammer in upright position.
3) one in the chamber, safety on, hammer in upright position.
4) Not one in the chamber, safety off, hammer down.
My reasonings:
1) Cocked and locked and in SA ready to fire? No. Too easy for a good jolt to set the hammer flying or an AD
2) Locked and in DA ready to fire? Probably more safe. Choice of cocking hammer back for easy trigger pull and better accuracy or DA TP for down right "MUST FIRE NOW" scenario.
3) Locked but safety on? Most safe, but could be dangerous too. Could fumble for the safety, or forget about it. That would be bad. Safe way to carry, but for the time it takes to flic the safety off I could rack it just as fast.
4) Safety off and the hammer cocked but no bullet in the pipe is how i carry, especially around the house. With the hammer cocked there is less resistance on the slide making it easier to slide back. Is actually faster than fumbling with the Slide safety. Also a good "Hey I just chambered. Stop or I'll shoot you!" indicator to the BG.
Look, maybe it's not the "Best" way to carry, but I'm still carrying. I'm not defenseless and those around me are more safe because of that. Whether there is one in the pipe or not, there are 15-17 right there and another 10-12 right beside it waiting to go.
Maybe it's irrational to "fear" the gun going off. I've tried to explain that to the women of the house, one of which would feel more safe if it was locked in a safe, upstairs. I don't fear it going off because I know my pistol and I know how it will be safe to carry it. But I don't carry it loaded because a half-second isn't going to make much difference. This isn't the matrix and I can't dodge bullets, but I can jump for cover as I'm drawing my pistol if that's the case. Otherwise I will more than likely have time to draw, rack, and aim.
This reminds me of the movies or television when a SWAT team enters a room to take down a bad guy and you can all hear them rack their slides when they enter the room. Come on, that's ridiculous.
Carry however you want, but I think pointing a gun at a bad guy will give him the same message as racking your slide. Also keep in mind that you'll likely need two hands to rack your slide. You could be in a situation where you've only got one hand.
