These are actual McMaster screws.https://imgur.com/a/5FcBSue
After much research, I found that the screws holosun provides for the optic are not deep enough to fit on the m&p 2.0 pistols with the standard plate on there.
I found that they simply wouldn't grab enough threads in the pistol to stay mounted properly. Then I tried longer screws that came with the gun. No dice, all the longer screws are designed for different optics. Not rmr or holosun.
Smith and Wesson has in the manual to use the screws that trijicon provides if using an rmr. But doesn't address the holosun.
Holosun sent me the screws pictured on the right. [Which once again, weren't long enough.](https://imgur.com/a/8frBuyO

which explains the longest screws you can get away with for the platform.
So I ordered 50 screws. After 1k rounds and 2 separate events, one of which being a run and gun 5k, hence the dirt, here are the results

skeptical at first, because they don't sit exactly flush, but they seem to work well.
**Note** these are for m&p 2.0 core series pistols using the stock plate. I don't know how it would work for after market plates.
