Abstract
The invention provides an indirect firing fastener driving apparatus with adjustable firing power, including within a barrel holder, a barrel, a piston mounted in frictional contact within the barrel, and a pawl for retaining the piston. A ring, held against rotation in the barrel holder, is screwed onto the barrel. The ring cooperates with a free projecting into the barrel so that relative threading of the ring relative the barrel moves, through means of contact of the stop with the pawl, the position of the piston within the barrel when the barrel is pulled forwardly.
