In my opinion your going to be hard pressed to carry your XD with a light mounted on your weapon concealed, unless you wear a jacket all the time. Most of the holsters designed for carrying your weapon with a light mounted at all times are designed for duty belt's or for drop-leg carry.
Since you are wanting to go from belt carry to drop leg your choices are limited. You will be hard pressed to find a leather holster that will fit the bill. You might look at Blackhawk's Serpa (they do not have a Serpa holster to fit an XD with a light mounted at this time) or Blackhawk's Omega Elite Holster VI or even Eagle Industries SAS Mark V Holster with Light Mount Similar Products. The last 2 holsters you can pull the extender off and mount the holster to your belt.
I carry my XD or my Sig P-226R in a Milt Sparks VM-II or a Galco Combat Masters with a Surefire X300 in my pocket or on a Blackhawk CQC Dual Rail Accessory Belt Loop or a CQC Dual Rail Accessory Paddle with a spare magazine.
Hope this helps. In the past 25yrs I have tried and replaced more holsters then I can remember. It is going to take time to find what works for you. Sometime what you want and what you can find are totally different. Good luck.
