Cowboy Guns posted this on their Facebook Page. Their buddy had a squib in his KKM barrel. According to Cowboy Guns, Glock will fix the gun for $225 and KKM will replace the barrel. Not sure if this was with reloads or factory ammo. However it is very nice that Glock and KKM are willing to help out the owner. Pretty interesting malfunction. As you can see the pressure took the path of least resistance. It blew the barrel up and through the port in the slide.
