Questions & Answers
Is this the right plate to buy for a p320 x full size for Acro p2? Expert Answer

No, the Agency Arms Agency Optic System AOS Optic Plate is designed for a slide with the Agency Optic System (AOS). It is not compatible with the factory optic cut. The C&H Precision Weapons Optics Adapter Plate (linked below) will adapt your P320 slide to accept optics that use the Acro footprint.

I bought the Romeo zero red dot sight but didn’t realize it was for the p365. Will this allow the Romeo zero to fit on a p320 ? Expert Answer

No. This plate is specifically designed to work with Agency Arms P320 slides and does not fit factory OEM Sig slides. The Romeo Zero will actually fit your P320 slide, but it will have space on all 4 sides of the optic which is not ideal and requires the screws to do all the work of holding the optic to the slide. My recommendation would be to purchase a larger Deltapoint Pro footprint optic such as the Sig Romeo 1 Pro, Eotech EFLX, or Leupold Deltapoint Pro.

sig aos plate by Reggiehightops, Verified Owner, June 30, 2024
Well made, and the price was very hard to beat. I put a rmr hd on it. It’s so well made you can turn the slide upside down without the mount hardware and the optic still doesn’t move. A plus in my book.
