ABSTRACT:
A gun includes a pivoting barrel assembly, a trigger/hammer double action firing mechanism, and a barrel/inline valve mechanism for firing projectiles. The pivoting barrel assembly includes a projectile-holding rotatable cylinder and an indexing mechanism for rotating the cylinder when the trigger is pulled. A hammer is cocked by a hammer link which is operatively connected to the trigger, and a cam on the hammer lifts the hammer link out of engagement with the hammer when the hammer reaches its cocked position. The valve mechanism includes a valve stem which is slidably mounted in a valve body. A pin portion on the valve stem extends through a valve seal and a valve seal retainer, and the valve seal retainer is retained in the valve body by retainer pins which extend through the body into a groove in the valve seal retainer. A detent housing is connected to the valve body, and a detent is slidably mounted with the detent housing. The detent is engageable with projectile chambers in the cylinder.
