File:Harpoon Gun 7223.jpg

Sometimes, a bow and a quiver of arrows aren't big enough to finish the job; you'll need spear-sized arrows. Thankfully, there's the Harpoon Gun for that.

Harpoon guns are used by divers. In fact, any firearm designed for underwater use is basically a miniature harpoon gun (normal guns simply won't work). Some can reel in anything the harpoon latches onto, thus working like a Grappling Hook Pistol.

Examples of Harpoon Gun include:

Comic Books
