This unique sidearm was also known as the "Grape Shot Revolver." It was developed in New Orleans in 1856 by Jean Alexandre Le Mat, whose manufacturing effort was backed by P. G. T. Beauregard, who became a general in the Confederate States Army. Fewer than 100 were made by John Krider of Philadelphia, Pennsylvania, in 1859, including the first 25 prototypes. It is estimated that 2,900 were produced in Liège, Belgium and Paris, France. The European-made pistols were shipped through Birmingham, England, where they were proofmarked.
