How do you plan to carry, IWB,OWB or shoulder rig? Several of the top manufacturers should be able to make one for you. The crossbreed style would be easy to adapt to the light guard add on. DeSantis Speed Scabbard
OWB on the carry question. I really like the lightguard. Its not awkward, it goes with the contour of the gun, its bright, the pressure switch is perfectly located. The only complaint I have is the switch (on off) on the front of the lightguard needs to "stick out" a little more for ease of use.
