A fastener driving tool comprises a tool body, a muzzle extending forwardly from the tool body and being displaceable into a ready-to-fire position, a magazine for holding fasteners coupled to the muzzle, and a follower within the magazine that biases the fasteners. The follower has a blocking surface that blocks the muzzle during fastener-empty condition and prevents the muzzle from displacing into ready-to-fire position.

What is claimed is: 1. A fastener driving tool, comprising: a tool body having an axis; a piston guided along said axis within said tool body for driving fasteners; a muzzle having a wall, and extending forwardly in the axial direction from said tool body, said muzzle being displaceable into a ready-to-fire position; a magazine for holding said fasteners and having an end coupled to said muzzle; said muzzle wall having an opening, there being a stop at said opening; a follower located in said magazine, and arranged to bias said fasteners through said magazine into said muzzle; wherein said follower has a blocking surface and at least a portion of said follower penetrates said opening in said muzzle wall when said magazine is in a fastener-empty condition, and wherein said stop of said muzzle wall contacts said blocking surface to prevent said muzzle from being displaced into said ready-to-fire position. 2. A fastener driving tool, as set forth in claim 1, wherein said stop is a surface on said opening of said muzzle wall. 3. A fastener driving tool, as set forth in claim 1, wherein said follower has a front surface and said blocking surface forms a part of said front surface. 4. A fastener driving tool, as set forth in claim 1, wherein-a front surface of said follower penetrates said muzzle wall during said fastener-empty condition, wherein said blocking surface forms a part of said front surface, and said stop has a surface that contacts said blocking surface and prevents said muzzle from assuming ready-to-fire position during fastener-empty condition. 5. A fastener driving tool, as set forth in claim 1, wherein said follower has a fastener-contacting portion that penetrates said muzzle wall during said fastener-empty condition. 6. A fastener driving tool, as set forth in claim 1, wherein said magazine extends laterally from said muzzle. 7. A fastener driving tool, as set forth in claim 1, further comprising a housing for said muzzle wherein said muzzle extends forwardly in the axial direction from said muzzle housing. 8. A fastener driving tool, as set forth in claim 1, further comprising a barrel housed coaxially within said tool body, wherein said barrel houses and guides said piston. 9. A fastener driving tool, as set forth in claim 1, wherein said piston is actuated by explosive power from a powder charge.
