P2000SK magazines and sizing
I just bought four more USPc /P2000 .40 mags today and used them immediately on two different P2000SK .40s. No problems with any of them. The X-Grips slid right into place and filled the gap nicely. That magazine combination is the correct choice for this application. If it did not fit, something else is going on.

Hope that helps.
