If you dont shoot IPSC or handguns at all for that matter, you have no business whatsoever making claims about the safety of the sport.
And if you say "Well what if you put the gun down and it tips over while you turned to do something?" Well then why did you leave the gun loaded jack-ass?
Anyone who actually shoots at a legitimate range knows this scenario is almost impossible given range-light rules and proving clear. A loaded gun is NEVER unattended, EVER.
