Just get an original Equinox in .40 and then a "9mm SIG SAUER Caliber X-Change Kit for the P226", and polish the sides of the kit slide to get a "two-tone finish" - Boom, you've got yourself an Equinox in 9mm. If that's too ghetto and cheap for you or you're concerned with leaving the polished metal exposed - get it Cerakote'd with their clear coat.
