Ok, so I contacted TruGlo directly and here is the email response I received:
"The TRUGLO sight sets for the Springfield XD and XDM will also fit the new Springfield XDS.
TG131XT TFO green/green
TG131XTY TFO green/yellow rear
TG231X Tritium ONLY
TG131X Fiber-Optic ONLY red front/green rear"
So there you have it.

The mission and my precious cargo are my concern. I will never surrender. I will never leave a fallen comrade to fall into the hands of the enemy and under no circumstances will I ever embarrass my country
