The surgical instrument of claim 1, wherein said opening is defined by a sidewall, wherein said projection is positioned against said sidewall in a first position when said projection is in said first clamping catch, and wherein said projection is positioned against said sidewall in a second position when said projection is in said second clamping catch. 3. The surgical instrument of claim 1, wherein said first clamping catch is positioned above said second clamping catch. 4. The surgical instrument of claim 1, wherein said adjustable pivot comprises a floating hinge. 5. The surgical instrument of claim 1, wherein said opening comprises a third catch configured to receive said projection when said second jaw is in an open position. 6. The surgical instrument of claim 1, further comprising a staple cartridge and a firing member, wherein said firing member is configured to deploy staples from said staple cartridge. 7. The surgical instrument of claim 1, wherein said second jaw comprises an anvil, wherein said anvil is configured to deform staples to a first deformed distance when said second jaw is positioned at said first gap distance, wherein said anvil is configured to deform staples to a second deformed distance when said second jaw is positioned at said second gap distance, and wherein said first deformed distance is different than said second deformed distance. 8. A surgical instrument, comprising: a handle;a shaft extending from said handle; andan end effector extending from said shaft, said end effector comprising: a proximal end;a distal end;a first jaw;a firing system, comprising: a push bar; anda cutting member, wherein said push bar is configured to be pushed distally to move said cutting member from a proximal position to a distal position, and wherein upon completion of a firing stroke, said push bar is configured to be pulled proximally from a distal position to a proximal position;a tissue gap setting system defining an adjustable pivot, wherein said tissue gap setting system comprises: a slot;a first seat defined in said slot; anda second seat defined in said slot;a second jaw comprising a projection movably positioned within said slot, wherein said second jaw is movable relative to said first jaw at said adjustable pivot, wherein said second jaw is movable into a first fully clamped position to clamp tissue between said first jaw and said second jaw when said projection is positioned in said first seat, wherein a first gap distance is defined between said first jaw and said second jaw when said second jaw is in said first fully clamped position, wherein said second jaw is movable into a second fully clamped position to clamp tissue between said first jaw and said second jaw when said projection is positioned in said second seat, wherein a second gap distance is defined between said first jaw and said second jaw when said second jaw is in said second fully clamped position, and wherein said first gap distance is different than said second gap distance; anda locking mechanism configured to maintain the relative position between said first jaw and said second jaw when said jaws are in said first fully clamped position and maintain the relative position between said first jaw and said second jaw when said jaws are in said second fully clamped position. 9. The surgical instrument of claim 8, wherein said slot is defined by a sidewall, wherein said projection is positioned against said sidewall in a first position when said projection is in said first seat, and wherein said projection is positioned against said sidewall in a second position when said projection is in said second seat. 10. The surgical instrument of claim 8, wherein said first seat is positioned above said second seat. 11. The surgical instrument of claim 8, wherein said adjustable pivot comprises a floating hinge. 12. The surgical instrument of claim 8, wherein said slot comprises a third seat, and wherein said projection is positioned in said third seat when said second jaw is in an open position. 13. The surgical instrument of claim 8, further comprising a staple cartridge and a firing member, wherein said firing member is configured to deploy staples from said staple cartridge. 14. The surgical instrument of claim 8, wherein said second jaw comprises an anvil, wherein said anvil is configured to deform staples to a first deformed distance when said second jaw is positioned at said first gap distance, wherein said anvil is configured to deform staples to a second deformed distance when said second jaw is positioned at said second gap distance, and wherein said first deformed distance is different than said second deformed distance. 15. A surgical instrument, comprising: a handle;a shaft extending from said handle; andan end effector extending from said shaft, said end effector comprising: a first jaw;an adjustable pivot comprising a window, wherein said window comprises a first window portion comprising a first height and a second window portion comprising a second height, and wherein said first height is different than said second height;a firing system, comprising: a push bar; anda cutting member, wherein said push bar is configured to be pushed distally to move said cutting member from a proximal position to a distal position, and wherein upon completion of a firing stroke, said push bar is configured to be pulled proximally from a distal position to a proximal position;a second jaw comprising a fulcrum movably positioned within said window, wherein said second jaw is movable relative to said first jaw about said adjustable pivot, wherein said second jaw is movable into a first closed position when said fulcrum is positioned in said first window portion, wherein a first gap distance is defined between said first jaw and said second jaw when said second jaw is in said first closed position, wherein said second jaw is movable into a second closed position when said fulcrum is positioned in said second window portion, wherein a second gap distance is defined between said first jaw and said second jaw when said second jaw is in said second closed position, and wherein said first gap distance is different than said second gap distance; anda locking mechanism configured to maintain the relative position between said first jaw and said second jaw when said jaws are in said first closed position and maintain the relative position between said first jaw and said second jaw when said jaws are in said second closed position. 16.
