A hammer gun is a archaic form of a archaic device. Some would consider a hammer gun person as a purist others as a fringe person. Which is a polite way to call one a nut. Either way a hammer gun is fun to shoot and this is or should be a fun hobby.

I like the early hammer guns more than the later ones. Something about those dolphin or high style hammers just look cool. Later ones are more compact, more utilitarian, and just not as gaudy.
