Authorities in the Australian state of Victoria are investigating defective gun holsters, which are still being used by area police.

According the The Age, an officer was shot dead after a routine traffic stop by his own firearm in 2005. The commanding officer allegedly knew the holsters to be defective and potentially fatal. While some say officers were not warned of the danger, one officer told the paper that the security clip on his holster often opened without him noticing, happening “more times than I can think.”

If any good could come out of this story, it would be underlining the importance of a quality gun holster that would never impede police officers’ ability to defend themselves and others. Whether your holster is made out of leather, kydex or any other material, always double check that it’s working properly before using it on the job.
