I am still new to red dot pistol sights and the nomenclature. I have a PSA Rock 5.7 on the way and want a red dot sight for it. I am trying to figure out compatibility.

This is the gun.

This is the comment on Optics: This 5.7 Rock optics-ready slide is cut for direct mount Shield footprint optics, excluding Leupold Delta Point Pro. Included are two adapter plates, one for RMR optics, and one for Docter cut optics.

Is this sight direct mount ready? If not what do I need to make it work?

Specs say direct fit for a Shield footprint. The sight says RMSc which is the compact version of the Shield. Hole spacing is the same so the sight should fit the gun.

What had me a bit confused was the Shield to RPSc. It's a new language to me, and with them calling it two different things, I didn't know.

Thank you.

Be prepared to scrounge for screws that fit, depending on the sight maker. I had to cobble together a set for my S&W 5.7, then called the sight maker who promptly sent out a set. This was for a HOLOSUN HS507K-X2.

Go easy on that screwdriver!

I would call PSA and get some recommendations for suitable sights. Their pistol, so they should know.

What about a trigger upgrade..?


11 lbs?

LMAO

Alright folks, I got the gun in and looked at the footprint.

PSA calls this a "Shield" footprint.



The specs for the above Riton Optic say that it fits a Shield RMSc Type Footprint

Are there different Shield footprints, because when I look up a Shield RMSc footprint, it looks nothing like the footprint on my gun.

What gives?

I can't help with that one.

I'll say this, the whole RDS industry foot print mounting thing is a cluster.

When it says Shield footprint, there is just 1 style. I prefer RMR footprint, but it's apples and oranges. It is nice that Riton sees the need and makes Red dots with both footprints. The 3 Tactix MPRD is made with a Shield Foot print. https://ritonoptics.com/product/3-tactix-mprd/

I ordered the Riton, and it should come in this week. The optic has 4 round sockets to accommodate 4 posts on the slide. As you can see, my slide only has 2 posts and they aren't round.

Looks like a "K Series/Modified RMSc" footprint.

The Riton MPRD arrived today. It bolted right up. Without the mounting screws, there is some play given the shape of the posts on the slide, but I don't think it's an issue.

These optics are $99 at CDNN.
