zero issues with XS Sights 24/7 Express sights on P models?

[LDM]

I am essentially cross posting from the TP forum because this issue is as much about the P models as the TP. The P & CW forums are more active and tap into wider experience.
I recently purchased a TP45 and would like to put XS Sights 24/7 Express sights on this weapon.
However when I called XS Sights, they said they were not sure if their sights would have the same zero with full size (i.e. P45 & TP 45) weapons. Clearly implied was that they tested the PM models but not the P (nor TP).
I know some folks have put XS 24/7 sights on P models from searching this forum, but I have not found any comments as to if there were issues with zero.
Has anyone placed these sights on a P model, and had any issue with zero?
Thanks.

If you follow the link it goes to a blog post about a P45 with those sights installed. No problem with zero.

Thanks, Ljutic. That was a good reference.
Also had reached out to Kahr, and they came back that the XS Sights 24/7 should shoot to zero with the P/TP pistols.
