FWIW, I DO point paintball and simunitions guns at people. That said, it is force-on-force training for the job, and we are very much practicing for the next level: Shooting real people with real guns!
Where your post turns to complete crap is the idea of doing it for fun. Don't get me wrong, I enjoy my training, but the Old West quickdraw is a legend that never was. Unlike in the movies, when you shoot a man in the chest with your .45 Colt, he will NOT fall down or fly through a plate glass window, but continue to SHOOT AT YOU!
In truth, Bob Munden himself could not likely survive unscathed from a live-ammo quickdraw with a good shot of average speed. Both men would get shot, as handguns are not powerful enough to let you live on the difference.
. . .And to prove some idiots would do it for real, check out the Great Falls Tribune. Two tried; one died. And these guys were buddies, not enemies.
QWICKDRAW IS A VALID SPORT, but winners and losers can be determined by timers safely, and without ignoring gun safety. And a +1 to Berk's idea.
You'll probably never NEED a gun. I hope you never do. But IF you do, you will need it worse than anything you've ever needed in your life.
IF we're not supposed to eat animals,
howcome God made 'em outta meat?
