Quick search didn't come up with anything, might be worthwhile trying to find a 3d printed option, or maybe a usw type kit that can be fitted to yours.
Or maybe a black hawk omnivore or one of the nuprol EU light bearing series might fit.
Unfortunately your pistol is relatively rare in use, even less so with a light fitted, so finding someone who's already overcome your problem is unlikely, only alternative is to take the pistol & light in to a retailer that stocks the holsters I've mentioned, again not necessarily feasible.
Best option, find an online retailer that will take a holster back if it doesn't fit your setup ?
