The last time I drew my 1911 for defense, here's how I held it.
I had my finger in the trigger guard.  But I kept the thumb safety engaged.  I would have had to disengage the thumb safety to fire, but I wanted to try it this way in a potential live fire situation, just to see if I felt more in control, and I was surprised to feel that I did.  Of course I didn't fire or even disengage the thumb safety, but I felt more natural having the gun "roostered" 'n locked, than having the thumb safety already disengaged, with my finger outside the trigger guard.  When I have to fire I have to quickly get my finger on the trigger, inside the trigger guard, and while I've never not been able to do this, it's felt a little harrowing, so that's why I tried it this other way, so my finger's already in there.  I'm going to try it again next opportunity.
Any thoughts?
