Folding firearm

A firearm comprising:

• a frame having a trigger assembly and defining a bolt passage;
• a barrel assembly pivotally connected to the frame for movement between an extended operable condition and a folded inoperable condition;
• the barrel assembly defining a barrel axis;
• a latch assembly operably connected to the frame and to the barrel assembly;
• the latch assembly including a latch operable between a first latched condition and a second unlatched condition;
• when the barrel assembly is in the operable condition and the latch is in the latched condition, the barrel assembly is secured in the operable condition;
• when the latch is in the unlatched condition, the barrel assembly is free to move away from the operable condition toward the folded condition;
• the firearm being free of other restraints on movement of the barrel assembly from the operable condition besides the latch, such that single-control release of the barrel assembly is provided;
• and
• wherein the latch includes a trigger block configured to enable operation of the trigger assembly when the latch is in the latched condition.
