That might explain it.
There are only 2 SA polymer pistols which don't have grip safeties, The Hell cat, a striker fired P365 competitor which is not part of the XD line, and the XD-E which is a DA/SA single stack which SA calls an XD for marketing purposes but which is not really part of the HS2000 / XD design lineage.
