, and pan, yet had an external catch as a half-cock safety, known as the "dog". This type of lock had no internal, half-cock loading position as the later flintlock mechanism contained. To load a firearm with a dog lock, the cock was secured with the external dog, preventing it from moving forward to strike the frizzen and begin the firing sequence. The user could then safely load the musket or pistol. To fire, the cock was moved to the full-cock position, which caused the dog to fall backward and no longer prevent the lock from firing. A pull of the trigger would then fire the piece. This fell out of favor with the British before 1720. Later flintlocks would contain no such catch, as the half-cock position had been created with the internal parts of the lock.Blackmore, Howard L. ''British Military Firearms, 1650-1850''.
