STI Staccato P Duo Red Dot install

Just got my brand new STI Staccato P Duo setup for red dot. I got everything out including the install kit but went to remove the cover plate and rear sight, but have no idea how to do this. There are no screws on top, underneath anywhere I can see to pull this plate. Any ideas?

Thanks

They're both on the rear sight. The rearmost being literally down in the sight.

That does not look like any STI Staccato plate that I have ever seen. Something is wrong. Plenty of YouTube videos on how to install your optic.

Is that a factory STI Duo cut slide or aftermarket? My Tactical 4.0 has the gen 1 HOST cut and it looks nothing like that. There should be 2 hex screws on the top of the plate holding it to the slide. The screws should be side by side, not front and back like your sight screws.

Could the plate screws possibly be concealed under the iron sights?!?!?

That is not the STI factory cover plate for a 2019 or 2020 Staccato P Duo. The cover plate is not even the same color as the slide.

I wonder if this gun started out as a Staccato P and someone sent the gun out for an aftermarket optic cut.

Something is terribly wrong or this is a joke.

You guys sound like a bunch of fudds. That is a 2020 Staccato P, and like I said the 2nd screw is literally located within the rear sight hole.

Pic of mine I picked up last week;

Copy that. I thought those screws were holding the iron sight on.

Any one have pics of this new mounting system disassembled?

Thanks! STI has come out with several optic cuts over the past few years, it’s hard to keep track of all of them!

Aren't there very detailed instructions in the range bag?

STI must have changed the plate design.

After reading this post, I sent a text to Tony Pignato and he confirmed that they had changed the way the plate mounts to the slide. I assume there are still appropriate holes under there for a DPP.

Take out the forward set screw that secures the sight. Then you have to knock the rear sight out of the dovetail. The screw that holds the plate on is now accessible. Not sure you have to remove the rear sight to back the main screw out, but mine was tight as snot and having not done it before, I was not sure I wasn't breaking something with the rear sight still on. CM

I have a brand new Staccato C2 DUO (Tactical) and have installed a Trijicon RMR. The factory DUO plate, same as a new P DUO, is removed by unscrewing the hex set screw “in” the rear sight, not the one in front of the rear sight. There is no need to remove the rear sight to do this.

Is this the fourth or fifth optic plate design for STI/Staccato? These guys change their products more often than a redneck changes their underwear.

So do you need to knock the rear sight out of the dovetail or can it be accessed from the top?
