The object of Low Ready (or any of the depressed carry positions) is just what it says- to provide a relatively safe muzzle orientation while keeping the pistol in hand. My suggestion would be that if you have Low Ready burned into your subconscious, don't screw it up by trying to over-write the hard drive for every fad that comes along.
Excellent post! I have been trained in low ready for over 30 years. It is kind of like the "new" handcuffing method they wanted to teach me once at "advanced" training.
