We have seen some unusual hand-guns in the past. The Triple Barrel Caricato revolver is quite a classic though. This revolver was manufactured in Italy in the early 20th century. It has 3 barrels and 18 chambers (6.35 x 16 mm semi-rimmed caliber). These do look a bit bulky to put in a pocket. At the same time, you get 18 shots with them. The revolver looks quite fun but you can’t find too many of these in stores though.
