I love these stories of cops pulling their service weapon from it's holster, or reholstering it; and somehow, having it just mysteriously go off by itself. These "stories", or more accurately fallacies, always sound like good script's for the X-Files or CSI to me.
I would imagine that a great majority of LE officer's, would not want to admit that they had their finger on the trigger causing an ND, as it's simply much easier to blame their equipement; effectively taking the heat off of themselves. It's really rather pathetic to blame a lifeless object for the careless actions of it's operator, when in reality, in almost every single instance (not all), the operator is indeed at fault!
I would be willing to wager, that even if a Glock were fitted with a NY+ 12-lb. trigger, and an officer using it had an ND, the pistol would still get the blame.
Frontsight's training facility has two documented ND's on record. One was with a 1911 that the operator forgot to "on safe" before reholstering, and the other was with a Sig P229 that the operator forgot to decock upon reholstering. Both subsequently shot themselves, one in the foot, the other in the thigh.
Most have either heard of or viewed the footage of, the female LVMPD officer who had an ND while covering a suspect with her DA Beretta, which has approximately a 14-lb. pull for the first shot; and a looooong stroke in DA mode. Also consider, that the average female has less grip and finger strength vs. the average male.
It would be refreshing to see officer's and agencies take responsibility for their action's. However, I suppose it would be bad for PR, to admit that their officer was the dangerous object, and not the pistol. And of course, depending on the resulting damage of the ND, an officer could very well lose their job should they fess' up.
