5 hole, I too have always carried "cocked and locked", but I think you'll agree, that the 1911 is a different cat in the way of combat pistols. I have always called it a "thinkin man's gun". Not to be condescending to anyone, but if your not used to a 1911 pistol, and you accidentally knock that thumb safety off, or forget to engage it, without realizing it, you are now pulling a "LIVE PISTOL" out of you waist band. I've even seen police officers lay them on a desk with the thumb safety off, and there was hell to pay when I saw it.
In this condition, if you get on that trigger, the gun will say go! The key to safely carrying a 1911 pistol, is PRACTICE, PRACTICE, PRACTICE. If you not willing to 'condition your MUSCLE MEMORY", by putting the time in, hammer down is the safest way to carry it. Anyone whom would disagree with that, doesn't know what their talkin about. I took a lot of officers off the range that wanted to carry the 1911, but weren't willing to put the time in. They were dangerous to themselves, and everyone around them.
It ain't a Glock, and it ain't a Sig DAO. A SINGLE ACTIONtrigger pull of 1/8" on some 1911 pistols and an INEXPERIENCED shooter is a scary thought.
Spirithawk I am sure is safe with guns, but I have never had him on my range, and it is a recommendation I give EVERYONE when I don't personally know their experience what the 1911.
By the way, my IWB holsters are much like yours, and just as worn, except I make my own. I agree it is the best way to carry concealed.
