A powder-actuated fastening gun including a housing in which a barrel assembly is mounted for movement between a locked position and an unlocked forward position. A percussion assembly is mounted in said housing for movement between a firing position and a fired position. A rod member, external of the barrel assembly, is moveable between a forward position and a rearward position. The rod member is releasably connected to the percussion assembly. A projection on the barrel assembly is adapted to engage the forward end of the rod member and move it from its forward to its rearward position as the barrel assembly is moved from its unlocked to its locked position. Actuating means are provided for disconnecting the percussion assembly and the rod member only when the rod member is in its rearward position. A second rod member may be provided which includes a safety catch to prevent disconnection of the percussion assembly and the rod member if the second rod member has not been moved rearwardly.
