Kirk, I don't see many instances where guns are just firing with no cause. (we know about your 870) Every single one of these holster discharges I have read about involved something pulling the trigger on the gun.
Then you must be new to INGO cause I post them up.
Gun CAN go bang without triggers being pulled. To deny the obvious is to risk our collective safety and right to carry.

The instances you post almost always have a cause other than the gun. A bowling ball hits the gun, someone drops their gun, a worn out holster pulls the trigger, someones shirt pulls a trigger, etc.
The guns aren't just going bang out of thin air.
