Are there any mods needed to use the SAS upper on a P365 lower with the manual safety?

I am doing this with an SAS upper and a Grayguns manual safety grip module. I've experienced no functional problems with this setup.

When I was looking at grip modules, some did not list the SAS as a candidate. The Slide Catch Lever and Take Down Lever are different on the SAS. I'm not sure if this would make a difference.

A purist might ask why you would add a protruding part (manual safety) to a SAS model. It didn't make a difference to me.
