Lionfish are an invasive species doing a lot of harm to underwater ecosystems. They’re basically the feral pigs of oceans reefs.
This underwater Glock-fishing video was originally made to see if this group of guys could shoot a Glock underwater, and once they realized it was possible, it developed into much more.
With no known predator, the lionfish has been eradicating baitfish all across the ocean. These guys do their part in slowing the lionfish devastation by bringing their Glocks underwater with them and firing away. The guns had to have a few modifications done to them, and then they were ready to go.
This video shows some really cool slow-motion footage of the guns being fired underwater, and they look like they shoot fine, just ask the lionfish.
