I thought it was a good and fair list.
For the most part, I would agree.
However, both the Volcanic and Browning Hi-Power don't belong on it. The Volcanic was a complete failure as a handgun. While the lever action design later evolved to become the action made famous by Winchester in their rifles, that is historically significant only for rifles, not handguns. As a handgun, the Volcanic was not practical, and was an utter failure.
The Browning Hi-Power was also not innovative enough to deserve mention.
I would replace those two guns with the first successful revolver: The Colt Model 1851 Navy Revolver, and the first successful pistol with a magazine in its grip: The Luger. They were both far more significant developments in handguns. The 1851 Navy Revolver was especially revolutionary in its day.
My Great-Great Grandfather carried a Navy Colt with him when he came to California from Missouri in 1854, and was forced to kill three with it during an incident on the trip. He was quite a man, and also had 12 children from one wife. Although one did die at childbirth.
Back then, a man armed with a 1851 Colt Navy had a huge advantage over any opponent. Having handguns go from 1 shot to 6 shots was a very substantial development indeed.
To not include that handgun on the list is a crime.
