Mounting screw size for G43X MOS red dot platform?

[ResJudicata]

Hello. I'd like to buy extra screws to mount a C&H Precision adapter plate to a Glock 43X for the Holosun 507K. I cannot for the life of me find what size these screws are. Can anyone help?

Might want to contact C&H Precision, get it straight from the horses mouth.

So I contacted CH Precision and bought the screw size they mentioned....they're the wrong size. I also contacted Glock....not helpful. Trying to see if anyone has experience and has bought screws that work.

Are these what they said, I’ve personally lost all faith in c&h. They nailed regular Glock mos plates for the many I’ve had but I’ve had several plates for other guns not fit the gun without filing, just out of spec. I’ve received plates with incorrect screws more than once. Then the last straw was a Steiner mps plate for a staccato (only reason I got it was because Dawson still hadn’t made one). Sent it right back, it had terrible anodizing, Machining looked like it was done by a toddler with a dremel, pictures showed serrations on the rear sight but didn’t have any.

^^^ That's disappointing to hear. They are probably growing to fast without new properly trained staff.

Any other company you would consider for plates and screws? C&H is my go to, but would like to see if there are other options if their QC continues to go down.

That’s what kind of sucks, not anyone I know if that makes so many options. I’ve used forward controls design and been happy with them. With staccatos I’ve used the Dawson plates and been very happy with them. Also got a couple slides just cut specific now.

So I know the Holosun EPS with adapter plate takes a 10 mm. Not sure if that helps.
