2000 rounds with the Staccato P DPO

Does anyone know if the Holosun 507 optics will fit on the factory plate for trijicon rmr/sro? It's the same footprint but Staccato sells a different plate for holosun.

Yes - it will fit. The screws are different since the Holosun requires shorter screws. If you order the RMR plate you’ll have to find different screws… and they have been discussed at length here.

In this thread or in the optic screw thread? Are the optic screws the same regardless of plates?

When I said “here”, I meant pistolforum. I’m not sure what specific optic thread… that said the screws I use for the Staccato/Dawson DPO plates are McMaster Carr stainless 6-32 but I need to get my hard drive to get the exact measurement/item number. I just used them to re-mount my 407C on my Staccato P that came back from some warrantee and add-on work.

Optic screws are not necessarily the same across different plates. Some plates may be threaded for different screws such as 6-40 or the plate may be thinner (requiring shorter screws) or thicker (requiring longer screws). There isn’t a ton of standardization right now.

Thank you I appreciate that! I'll do some searching around.

I pulled up my info... The screws I use for Holosun (407C/507C/508T footprint) to the Staccato (Dawson) plate are as follows:

McMaster-Carr 6-32 x 3/8" Stainless Steel (IP10 Drive), part number 92703A253.

I use stainless instead of alloy steel because the Holosun optics require a smaller diameter head than the RMR/SRO and the stainless fits while the alloy steel are too wide to seat consistently, especially with the titanium body 508T.

Between the Holosuns and the RMR, there's a 1/16" difference, so whatever any plate requires for RMR screws, take 1/16" off that and you'll have what you need for a Holosun.

I saw a P with the factory comp today. It was crazy long, no doubt modeled on the Glock 17L!

I can't imagine running a P with a comp at all let alone that factory one. I have a C2 and tried the threat cadre comp. I could not get the gun to run reliably. It pissed me off so much I ended up taking it off with pliers at the range and tossing it. Because I am a glutton for punishment I decided to try the parker mountain machine comp. It lined up pretty good and looks good, but I won't get to shoot it until possibly this weekend. I did pick up a pack of the factory springs for their comp, so maybe it will work better, but most of the youtube "influencers" claim the PMM comp runs with the factory springs.
