Colt 1855 10-Gauge Revolving Shotgun
The 1855 Colt revolving shotgun is a unique 10-gauge firearm featuring a five-shot cylinder and a distinctive rack and pinion lever system for cycling. Its side hammer design and the placement of ratchets on the axis pin are notable mechanical features. However, the design suffered from a significant cylinder gap issue, posing a risk of dangerous chain fires despite attempts to mitigate it.
