The .44 Special or .44 S&W Special is a smokeless powder center fire metallic cartridge developed by Smith & Wesson in 1907 as the standard chambering for their New Century revolver, introduced in 1908.〔Hawks, C. ("The .44 S&W Special" ) Chuck Hawks website. Accessed February 25, 2008.〕 ==Development history== In the late 19th Century American frontier, large .44- and .45-caliber cartridges were considered the epitome of handgun ammunition for self-protection and hunting.

Older black-powder ammunition was in the process of being converted to smokeless. Smith & Wesson's popular .44 Russian cartridge had established a reputation for superb accuracy and was a renowned target load, and they decided to use an improved smokeless powder version as the basis for the new round. Due to the lower energy density of the early semi-smokeless powders, prior efforts to convert the .44 Russian to smokeless had produced less than stellar ballistic performance. Smith & Wesson addressed this issue by lengthening the .44 Russian cartridge case design by , increasing the powder capacity by .〔(".44 S&W Russian" ) GMDR website.
