That's like the '97 shotgun, the cowboy era was gone when that came out.
I've got to disagree there. All the cowboys and settlers didn't sell their horses and wagons on January 1,1900 and buy Fords. The Native Americans didn't move into houses and drink tea with their pinky stuck up on 1-1-1900. They didn't close down the saloons and brothels and fire the lawmen as the towns had become so civilized. The banditos, renegades and criminals were still out there, the cattle still had to be herded and moved to the railhead. The major conflicts between settlers/military and the Plains indians had ended but there was plenty of wild west at the turn of the century, it just wasn't the same as 30 years before. The cap and ball guns became cartridge guns, muzzle to breech loader to Henrys to Winchesters, double guns to the 1887 to the 1897. The wagon train evolved into the iron horse which eventually became the Model T. Technology drives change, everyone wants an edge or the newest thing. Some cowboys, criminals and lawmen embraced the development of the double action revolver and eventually the 1911, others didn't. The change was a gradual thing. The cowboy era had certainly changed by 1897 but was not gone.
