Remington and Marlin soon released their own rifles and pistols which chambered the round, and Colt also offered it as an alternative chambering in its popular Single Action Army revolver in a model known as the Colt Frontier Six-Shooter. Settlers, lawmen, and cowboys appreciated the convenience of being able to carry a single caliber of ammunition which they could fire in both pistol and rifle. In both law enforcement and hunting usage the .44-40 became the most popular cartridge in the United States and to this day has the reputation of killing more deer than any other save the .30-30 Winchester.
