The .38 Long Colt, also known as .38 LC, is a black powder cartridge introduced by Colt's Manufacturing Company in 1875. In 1892, it was adopted as a standard military pistol cartridge by the United States Army for the Colt M1892 revolver. The metric designation for the .38 Long Colt is 9.1×26mm. It is slightly more powerful than the .38 Short Colt, also known as .38 SC. The original .38 SC and .38 LC differ in case length, bullet diameter, weight, and design and are not interchangeable; however, modern production .38 SC ammunition is now loaded with a smaller, internally-lubricated bullet which can be fired from firearms chambered in .38 LC or .38 Special. The modern .38 LC can be fired from a .38 Special firearm, but not from a firearm designed for the .38 SC, since the case length is too long.^[2]
