A pneumatic gun with separate hammer and recock piston function. Separate structures are provided for an impacter and for a recock piston. In one embodiment, the recock piston directly engages the impacter during recocking. The impacter is latched in a cocked position, while the recock piston and bolt are returned to a closed bolt position after recocking the impacter, in readiness for firing. The gun fires from a closed bolt. Upon release of the impacter sear, the impacter opens a normally closed valve, directly or indirectly, to discharge compressed gas for firing a projectile and for recocking the gun. Various impacter shapes, recock piston shapes, and valve structures and operation are feasible while achieving the advantages of firing from a closed bolt in a semi- automatic gun.
