Only if you don't bottom it. I assume you are doing so (as I do also) with
your first fixing.

The jaws don't need to "grip" anything unless you're using them in a
non-dovetail recess. Check the pin jaw setup at the pages I referenced.
Even there, the difference is in the bottoming.

In my experience the diameter of the recess is more important than the
angle of the dovetail. I say that because I do a lot of first fixings
into a shallow hole drilled with a forstner bit, so I have no dovetail
at all.
