A fastener driving tool for driving fasteners toward a work surface comprise s a body having a forward end, a rear end, and a cylinder with an axis, a pist on mounted within the cylinder, a power source for driving the piston axially forwardly, a driver blade extending axially forwardly from the piston, a nosepiece extending axially forwardly from the front end of the tool body, wherein the nosepiece encloses a drive bore for guiding the fasteners and th e driver blade toward the work surface, there being an opening into the drive bore for the fasteners, a magazine for guiding the fasteners to the opening. In one aspect, the magazine and the nosepiece are fixed with respect to each other, and the tool includes a fastener guide that extends axially forwardly from the nosepiece and moves with respect to the nosepiece between an extend ed position and a retracted position. In another aspect, the opening into the drive bore provides a small clearance through which the tips can pass, where in the opening is long enough to accommodate fasteners of at least two differen t lengths.
