John Pedersen was one of the more prolific and successful gun designers in American history, having even been described by John Moses Browning as "the greatest gun designer in the world". And yet, many people only know about Pedersen from his unsuccessful togglelocked rifle or his WWI Pedersen Device that never saw action. In truth, Pedersen's work included a number of very successful sporting rifles and shotguns that many shooters would still recognize today. While looking through the guns at Rock Island on my most recent trip there, I realized that they had examples of virtually every one of Pedersen's guns so I figured I should do an overview of the man's work.
