Confederate Revolver Le Mat 1856. The LeMat revolver was a .42 or .36 caliber cap & ball black powder revolver invented by Dr. Jean Alexandre LeMat of New Orleans, which featured an unusual secondary 16 gauge smooth-bore barrel capable of firing buckshot. It saw service with the armed forces of the Confederate States of America during the American Civil War of 1861–65.
This shotgun from Serbu was not made for bird hunting. The Super Shorty by Serbu could possibly be the shortest 12 guage pump shotgun available. It is based on the Mossberg Maverick but available for the Mossberg 500 or the Remington 870 for an extra charge. Holds 2-2 3/4 shells and then one in the chamber.:
