Well, it's my thinking that if the gun is functioning properly, you have to really design the holster for it to unintentionally fire. That is, if the holster is molded to the gun, even with heavy molding in the trigger guard, the rest of the molding will prevent the gun from moving downward in the holster causing it to unintentionally discharge. You would have to have really deep molding in the trigger guard and push the gun through the stitches to cause it to fire. And that's just not feasible and would suggest a peoblem with the operator not the holster
