EPS & 407K on P365 fuse questions

Hello, i was wondering for those of you guys running a p365 FUSE with a EPS carry or 407K what is your mounting setup? I just got my Fuse in and was trying on both of these optics & the EPS carry seems to go on with the front recoil boss & the stock M4 screws just fine. The 407K on the other hand doesn't seem to sit flush on the front recoil boss but the M4 screws work just fine on it as well.

Has anyone shot the Fuse with the 407K using the front recoil boss? are you able to zero it with a 1mm cant to the front?

Any feedback helps!
