Handgun sight pusher

1. A handgun sight pusher comprising:

an upper frame having a screw drive within an internal adjustment cavity and a pusher block rotatably engaged with the screw drive, wherein the internal adjustment cavity includes a transitory space and a rotation space; and

a lower frame connected to the upper frame and having a gun slide channel for receiving a gun slide and a plurality of side clamps for securing the gun slide in the gun slide channel,

wherein rotation of the screw drive causes the pusher block to move along the screw drive,

wherein movement of the pusher block along the screw drive transitions the pusher block between the transitory space and the rotation space,

and wherein the internal adjustment cavity is structured and configured such that the pusher block retains its orientation in the transitory space and rotates freely within the rotation space.

2. The handgun sight pusher of claim 1 , wherein the pusher block includes at least two pusher flanges on a top of the pusher block that are separated by a bridge.

3. The handgun sight pusher of claim 2 , wherein the pusher block includes at least two pusher flanges on a bottom of the pusher block that are separated by the bridge.

4. The handgun sight pusher of claim 1 , wherein at least one each of the plurality of side clamps are located on either side of the gun slide channel and are in horizontal alignment with each other.

5. The handgun sight pusher of claim 1 , wherein the gun slide channel includes a bottom channel gap.

6. The handgun sight pusher of claim 1 , the upper frame further including a vertical hold down for clamping the gun slide between the vertical hold down and the gun slide channel of the lower frame.

7. The handgun sight pusher of claim 1 , wherein the lower frame connects to the upper frame by frame bolts positioned to flank the gun slide channel.

8. The handgun sight pusher of claim 7 , wherein the upper frame and the lower frame have aligned vertical bores through which the frame bolts penetrate, and further wherein the frame bolts are threadedly connected to the threaded vertical bores of the lower frame.

9. The handgun sight pusher of claim 8 , wherein the vertical bores each additionally house a spring.

10. The handgun sight pusher of claim 1 , wherein the upper frame includes at least one horizontal bore through which the screw drive penetrates, and further wherein the screw drive protrudes out horizontally from the upper frame and through the horizontal bore.

11. The handgun sight pusher of claim 10 , wherein an exterior end of the screw drive is attached to a hand crank that is used to rotate the screw drive.

12. The handgun sight pusher of claim 11 , wherein the screw drive, the pusher block, and the hand crank all rotate around a first axis.

13. The handgun sight pusher of claim 11 , wherein the hand crank includes a socket drive.

14. A handgun sight pusher comprising:

an upper frame having a screw drive within an internal adjustment cavity and a pusher block rotatably engaged with the screw drive, wherein the internal adjustment cavity includes a transitory space and a rotation space; and

a lower frame connected to the upper frame and having a gun slide channel for receiving a gun slide and a plurality of side clamps for securing the gun slide in the gun slide channel,

wherein:

rotation of the screw drive causes the pusher block to move along the screw drive,

movement of the pusher block along the screw drive transitions the pusher block between the transitory space and the rotation space,

the pusher block retains its orientation in the transitory space and rotates freely within the rotation space, and

the pusher block includes at least two pusher flanges on a top of the pusher block that are separated by a bridge.

15. A method of adjusting a handgun sight of a gun slide, the method comprising:

rotating a screw drive in a first direction until a pusher block that is rotatably engaged with the screw drive moves from a transitory space into a rotation space;

rotating the screw drive in the first direction until the pusher block freely rotates 180 degrees in the rotation space;

rotating the screw drive in a second, opposite direction until the pusher block that is rotatably engaged with the screw drive moves from the rotation space to the transitory space such that the pusher block is now 180 degrees rotated from its starting position;

rotating the screw drive in the first or the second direction until the pusher block makes contact with a sight of a gun slide; and

continuing to rotate the screw drive until the sight is moved into a predetermined position.

16. The method of claim 15 , the method further comprising:

positioning a gun slide in a gun slide channel; and

securing the gun slide in the gun slide channel using a plurality of side clamps,

wherein the sight is aligned with the pusher block when the gun slide is secured in the gun slide channel.

17. The method of claim 16 , the method further comprising vertically securing the gun slide in the gun slide channel using a vertical hold down to clamp the gun slide between the vertical hold down and the lower frame.

18. The method of claim 14 , wherein the pusher block includes at least two pusher flanges on a bottom of the pusher block that are separated by the bridge.
