a mounting flange inserted into the rear cutout of the slide cover, said mounting flange comprising:

a top planar surface comprising fastening devices to attach various firearm accessories; and

a bottom surface comprising a first anchor leg containing a hole and a second anchor leg containing a hole; wherein the first anchor leg hole and the second anchor leg hole are in alignment with the right side cutout and left side cutout of the slide cover and said anchor legs are spaced apart to straddle an underlying slide mechanism, said slide mechanism containing a hole in alignment with the right side cutout and left side cutout of the slide cover; and

a flange lock pin inserted into the right side cutout, the first anchor leg hole, the hole of the underlying slide mechanism, the second anchor leg hole and the left side cutout of the slide cover.

2. The accessory attachment system of claim 1 , wherein the rear cutout of the slide cover is enlarged for other accessories that attach to the slide mechanism.

3. The accessory attachment system of claim 1 , further comprising a second rear cutout in the top surface of the slide cover for accessories that attach to the slide mechanism.

4. The accessory attachment system of claim 1 , further comprising a side cut-out section that is in alignment with a shell ejection port of the slide mechanism.

5. The accessory attachment system of claim 1 , wherein the flange lock pin and the left side cutout of the slide cover are threaded.

6. The accessory attachment system of claim 1 , wherein the mounting flange is removable.

7. The accessory attachment system of claim 1 , wherein the slide cover is made from a durable, lightweight polymer material.

8. The accessory attachment system of claim 1 , further comprising a front cutout for other accessories that attach to the slide mechanism.

9. The accessory attachment system of claim 1 , said mounting flange further comprising at least one set screw inserted into the top planar surface of the mounting flange.

10. The accessory attachment system of claim 1 , said mounting flange further comprising at least two set screws inserted into the top planar surface of the mounting flange.

11. The accessory attachment system of claim 10 , wherein one of the at least two set screws is inserted into the top planar surface of the mounting flange behind the inserted flange lock pin and the other of the at least two set screws is inserted into the top planar surface of the mounting flange in front of the inserted flange lock pin.

12. The accessory attachment system of claim 1 , said slide cover further comprising various grooving patterns located on the front end and rear end of the slide.

13. A method for adapting mountable accessories to a slide-action handgun, comprising:

replacing a factory slide cover with an accessory attachment system comprising:

a slide cover comprising:

a front end, a rear end, a top surface, a right side and a left side;

a right side cutout located on the right side of the slide cover that is aligned with a left side cutout located on the left side of the slide cover and a rear cutout in the top surface of the slide cover;

a mounting flange inserted into the rear cutout of the slide cover, said mounting flange comprising:

a top planar surface comprising fastening devices to attach various firearm accessories; and

a bottom surface comprising a first anchor leg containing a hole and a second anchor leg containing a hole; wherein the first anchor leg hole and the second anchor leg hole are in alignment with the right side cutout and left side cutout of the slide cover and said anchor legs are spaced apart to straddle an underlying slide mechanism, said slide mechanism containing a hole in alignment with the right side cutout and left side cutout of the slide cover; and

a threaded flange lock pin inserted into the right side cutout, the first anchor leg hole, the hole of the underlying slide mechanism, the second anchor leg hole and the left side cutout of the slide cover;

securing an accessory to the top surface of the flange using the fastening devices; and

securing the bottom surface of the flange to the slide mechanism by inserting the flange lock pin into the right side cutout, the first anchor leg hole, the hole of the underlying slide mechanism, the second anchor leg hole and the left side cutout of the slide cover.

14. The method of claim 13 , wherein the fastening devices are configured to a pattern matching a mounting bracket of a specific firearm accessory.

15. The method of claim 14 , further comprising:

unfastening the accessory from the mounting flange and removing the accessory from the firearm;

removing the threaded flange lock pin and removing the mounting flange from the rear cutout;

replacing the mounting flange with a second mounting flange configured to a different fastening pattern matched to an alternate accessory;

inserting the flange lock pin into the right side cutout, the first anchor leg hole, the hole of the underlying slide mechanism, the second anchor leg hole and the left side cutout of the slide cover; and

securing the alternate accessory to the second mounting flange.
