Blackhawk makes level 3 light bearing holsters.

Video wouldn't load for me but I'll take your word on it showing Al's holsters.

Those photos are both stock/file photos and don't necessarily represent the holsters from the incident.

Link 3 only contains one holster related discharge.

The 4th incident isn't holster related.

I'm not sure if you are intentionally misrepresenting these stories, or just didn't read them.
