Flat Head Socket Screw, 6-40 x 1/2", Alloy Steel, Qty. 2

These are the screws you need to mount your Trijicon or Holosun 507C red dot sight to your OEM SIG P320 slide with the RMR hole-pattern. A few models of OEM SIG P320 slides come predrilled with the RMR hole pattern, but utilize 6-40 threads (AXG Scorpion, Legion, Pro-Cut & Pro slides). 

It may be necessary to cut these to length for proper fit and to avoid interference with the extractor spring. Requires 5/64" Allen wrench (not included).

Includes: 2 #6-40 X 1/2" flat head, socket head screws.

No other tools or pins are included. Oil or anti-seize is recommended before installing. Use Loctite and follow red dot manufacturer's torque spec.

COUNTRY OF ORIGIN: Taiwan (may vary, depending on availability).

    #6 - 40 1/2” screw set

    Posted by Josh Sumersett on Jan 26th 2024

    Sig P320 axg have a #6 40 1/2” screw for RMR footprint. Not sure if it was just my optic or what. I had to file down the circumference of the screw head to be able to get the optic seated. I believe screws have a small hole space for the proper torque so I can’t complain about it. I do feel they would be better with a size or two bigger . I stripped one screw before I filed down the sides. Over all they work for their intended purpose. Buy more than one set so you have room for error.

    I purchased these to secure my red dot to my P320 Spectre Comp and they worked out perfectly! I didn’t have to trim any length off at all. I recommend them for any Sig P320 slide.
