MK9 frame vs. MK40 frame?

[Redstate]

Is there any difference at all between the MK9 frame and the MK40 frame? Kind of wondering if the 40 is a little beafier.

Most of the difference is in the Slide. The slide is a little taller and heavier ... frame dimensions are the same.

Thanks. Do you know whether the ejector is the same for the .40 and the 9. I know that on Glocks they are different.

Answering my own question here. Went to the Kahr website and the part number for the .40 ejector is different from the part number for the 9mm ejector.
