Let’s just say for arguments sake, you have a serpa, and a Glock, you draw put your finger in the trigger guard apply the 5 1/2 pounds of pressure on the trigger to set the gun off, who’s fault is it ? Blackhawk for making the holster, Glock for making a pistol without an external safety or yours for pulling the trigger ??
Well it would be again both the holster and the user.
Holster because of the design flaw and the user for using garbage equipment that has a known design flaw
