oldolds442, I have no idea why I'm participating in this debate. Perhaps it's because I have no life.
During the mid-1980's, I shot IPSC a lot. Everyone used souped-up wondernines that I would never have trusted my life to. They were good for scoring, but they malfunctioned regularly. Fortunately, the shooter got to adjust his racegun and come back next week.
My 6" S&W 586 in a shoulder rig made a lot of people nervous, and I had to start at the far left area of the range, for obvious reasons.
The reason I carried and competed with that 586 was that it was the gun I carried. Didn't matter if I won the match. For me, it was defensive practice.
Fast forward to 2004. My 1911 horizontally-carried muzzle may "sweep" hundreds of people a day, but the likelihood of the hammer being able to push through the leather thumb-break tab and hit the firing pin is absolutely zero. It won't happen.
If I find myself in a situation where I have to draw, "sweeping" someone is not an issue high on my list. Chances are that in that situation, every innocent is already being "swept " by the bad guy. Besides, I've already trained to keep finger off trigger until the gun is near or on target.
