At the age of 65, Smith retired from the company and sold his share of the business to Wesson, making him the sole owner of the firm. In the late 1800s the company introduced its line of hammerless revolvers, a style that is still produced. In 1899, Smith & Wesson introduced what is arguably the most famous revolver in the world, the .38 Military & Police (renamed the Model 10 in 1957). This revolver has been in continual production since that year and has been used by virtually every police agency and military force around the world. Death and legacy Wesson remained active in the firm until his death. Wesson died at his home in Springfield, Massachusetts, on August 4, 1906—following a four-year illness, he succumbed to "...heart failure, superinduced by neuritis."
