S&W's innovative concealed-hammer top-break revolver with a unique grip safety that prevented firing unless the grip was fully squeezed — hence "lemon squeezer." Designed for safe pocket carry without a dangling external hammer. The top-break action simultaneously ejected all five cases. Over 90,000 made across 5 models from 1887-1940. Theodore Roosevelt was said to have carried one.
