IMO, it's not so much the Con3 that is the problem...even WE Fairbairn (or was it Rex Applegate?) recommended carrying the 1911 in Con3 and racking the slide as part of the draw stroke instead of cocked-n-locked. It's the fact that the OP isn't carrying his firearm that way because of some well-thought-out, if not misguided, 'tactical' advice, but instead because of unfamiliarity with the platform and carriage of a firearm in general, and/or a shoddy holster.
Yeah, that's the issue.
While I don't like condition 3, I can respect those who have considered the pros and cons, and who train diligently in drawing, charging the chamber, and firing, both two-handed and one-handed. I still think it takes less time to learn to safely handle condition 1, but their approach is defensible.
However, when folks think "I'll have time to charge the chamber" that's where they step off the reservation. No, you may not have time to charge the chamber, particularly if you haven't trained that way extensively. You may well learn that you've been selected when the guy who asks you for a cigarette punches you in the mouth.
If you haven't trained extensively in drawing and charging the chamber, it is quite likely that you'll grab your gun, draw, pull the trigger and hear a click when you expected a bang. At that point, an "exciting" day might get far more "exciting."
Think through the issue, choose a condition, train that way, and fight that way. And for goodness sakes, get a real holster.
