I have a shoulder holster that I got from the 1500 the accepts a light. Don't remember the brand, but he had a stand with TONS of canvas holsters. When I get home, I'll check out for labels.
Any custom Kydex holster maker can do up a holster for a light-bearing gun, if they don't already catalog one. What style are you wanting (IWB, OWB, shoulder, retention/duty, etc)?
And yes, molded or fitted holsters (be they leather or kydex) are typically light-specific.
