Why do we get several reports of “holstered” striker fired safe pistols experiencing ND’s?
You answered your own question.
Nice deflection, but it still doesn't answer the question. Can't you just admit that striker fired guns w/o any other forms of safeties besides a long trigger pull carry a higher risk? Every time an ND comes up, there's a whole host of comments like, "That guy is a dumbass!" as if to say, "it can happen to that guy, but not to me, because I'm not a dumbass." Who knows, maybe this guy made those same comments in the past. I'm not excusing him, but I'm also not going to be so quick to condemn, because doing so let's my guard down. ND's happen to well trained folks, so I better be extra cautious so it doesn't happen to me. Pretending I'm immune won't make me any safer. I also better realize that some guns I carry have a greater risk. That's a risk I'm willing to acknowledge and accept. Furthermore, AIWB may not be more prone to ND, but the consequences of one are more severe - your twig and berries, your choice. Admit the risk exist, and accept it if you so choose.
And why isn't anyone asking the real question, "Why was this guy coonfingering his gun to begin with?"
I typically insert my pistol into it's holster before putting the holster into my pants, thus avoiding the shirt tail problem.
