V1223 Sgr is among the brightest magnetic cataclysmic variable in the 1--10 keV range, with a 3.36 hr orbital period and a 745.6 s spin period. Here we report the preliminary results from our Chandra HETG observation, performed on 2000 April 30/May 1, as well as from supporting observations with RXTE and ground-based telescopes. We have detected K\alpha lines of many atomic species in the phase-averaged HETG spectrum; in many cases, these constitute the first detection in this system. We find that the Fe L lines are substantially weaker than would be expected in a collisionally excited plasma. We will discuss possible interpretations of the line ratios.
