This books seems to come closer than most I have read, but the author seems to have missed that our founding father's owned quite a lot of firearms and Jefferson, at multiple times, mentioned that revolutionary war soldiers (who fought with privately owned guns) were crack shots because they had used guns since they were children.
Jefferson personally purchased 12 pounds of black powder in 1777 for his guns. Founders also mentioned fowling seasons in letters, which shows they obviously did hunt. There wasn't gun worship then, as there is now, but it was obviously a readily available tool since they had enough to win their first war with their own firearms- and that was after the British confiscation of firearms in 1775.
The author also claimed the second amendment was not meant to be utilized as a weapon for self defense, but as a hunting implement. Let's say for the sake of argument that is true. Then the argument may be made that gun owner rights are still being violated, as there is a LARGE anti-hunting movement seeking to ban hunting. He curiously makes no mention of that.
As it so happened, I had just read "The Gun and Its Development" by W.W. Greener (a British rifle manufacturer) written in 1910. Greener's exhaustive history of the firearm directly contradicts many of Spitzer's claims about early firearms, which is interesting as Greener was British and therefore not part of the American firearm debate, whose book was written well before the current firearm debate, and was further developed in firearms than the U.S.. at that point in history.
