Smith & Wesson
One of the most popular calibers during the Civil War was the .44 caliber. The partners realized they needed to produce a pistol in this caliber. By 1870 S&W introduced the .44 metallic cartridge which was a major improvement over the .44 percussion cap models used in the war. To use this new cartridge, the company introduced a larger pistol known as the Smith & Wesson Model 3. It featured rapid loading and reloading. The gun was a personal favorite of Wyatt Earp. In 1875, at age 65, Smith sold his share of the company to Wesson. He still advised his former partner in business matters.
