I'm more than somewhat familiar with powder residue and I don't think this can be true except with revolvers. The cloud of powder is pretty well generally spread with all others.Keith B wrote:But not in large amounts on your hand and arm like you will if you pulled the trigger.

Also hard to see any gun firing when dropped from 2-3 feet on carpet, regardless of impact angle.
So sad either way.
With a revolver there's an explosive jet of burnt and still burning powder between the cylinder and barrel but with semi auto's that's not the case.
If you're within 3 feet of either the muzzle or open action you're going to get covered in residue.
I realize technology and testing have improved greatly over the last three decades but I don't believe it's gotten to the point we can definitively determine if someone actually fired a semi auto or if they were just extremely close when it went off.
