Which is it?

Sorry if this is a dumb question, but after looking at a few sites I can't get the answer I'm looking for. What PSI pen kit is interchangeable (or the same) as a Sierra? I can't seem to find it anywhere and I know there is a pen kit from PSI. Thanks for your help in advance.

I agree with Dave.
