First round is a heavier DA pull, so I don't fret where the muzzle points until the target is sighted.
I see a slight problem with that logic. I'm not going to recommend pointing a gun at your own innards, but if you want to, feel free. Stupidity tends to punish itself, eventually. But if you're not fretting about where it's pointing, and it gets pointed at me, the chances are good that
I'm going to fret.
As far as SOB carry, right or left holster is about the same as far as ease of draw. Safety of draw is another story. With a right hand holster, the grip will be up, insert thumb between body and gun, draw, bring gun around and forward. Muzzle tracks a small circle on the ground around you. With a lefty holster, you insert your whole hand between gun and body, draw, and the muzzle tracks a nifty line across your spine, kidney, guts, etc, until it clears, and is pointed downrange. Risky, but hey, it's your choice.
The other issues to SOB carry are that there exists a chance that you will slip and fall, and having a steel bar across your spine whilst doing so is another one of those risky ideas. It's not very comfortable to sit on a gun that way, and there is very little in the line of retention that can be done from that position.
