Flat Head Socket Head Screw, TORX, 6-40 x .41", Alloy Steel, Qty. 2
These are the CUSTOM screws you need to mount your Trijicon RMR or SRO red dot sight to your OEM SIG P320 slide with the RMR hole-pattern. Can be used for Holosun 507C, but may require trimming. Most current versions of OEM SIG P320 slides come predrilled with the RMR hole pattern, but utilize 6-40 threads (AXG, AXG Scorpion, Legion, X-Series, Pro-Cut & Pro slides).
It may be necessary to TRIM these to length for proper fit for the HOLOSUN 507C and to avoid interference with the extractor spring. Requires T-10 TORX wrench (not included).
Includes: 2 #6-40 X 7/16" flat head, TORX, socket head screws, alloy steel (custom machined to size and length, Approximate overall length of .410-.430").
No other tools or pins are included. Loctite is recommended before installing.
COUNTRY OF ORIGIN: USA (may vary, depending on availability).

Found the right ones!
These screws allowed me to mount a Holosun 507c to a Sig P226 or P220 Legion. In doing research online, nobody could find the right size screws for attaching a Holosun to a Sig 226. Even a gunsmith I visited could not find the right screws. These are the ones! I'm going to order a second pair.

P320 with Holosun HE507C
I was having issues with my optic coming loose, the screws that come with the HE507C that do fit, are WAY too short. Confirmed these screws do fit and solved the problem, HOWEVER, on the right side where the spring is underneath, I did have to use a grinder on that one to shorten it like 2-3 threads.

Excellent service and product
The product was exactly what I needed. Worth the extra to buy the custom length screw. Highly recommend

Torx screws for legion227
I got my screws and put my Holosun 507c on and it was new never been shot so I loaded up the clips and went to shoot it and my shells wouldn’t go into battery and trying to get the shells out I scratched the top of my barrel and I noticed my ejector was was to hard and it seemed like my externals was locked up so I took it to a gunsmith and the screws was to long and he had to sand the screws down and then it worked fine but to pay that much for screws is fine I just was expecting them to fit especially when Holosun gave me ABslink and I talked to them to be sure to get the right ones and it caused about 3 days of stress . Buy the service was great and the shipping was fast and will use them again I just hope they fix this problem
