Well that Viridian site has a holster listed, but it's nylon and likely generically fits 'all'. The Viridian lasers may not be as popular as some of the older versions like the Surefires or the IT (Insight Tech) attachable sighting systems, so it may be harder to find. Molle Gear makes one, but again, it's pretty much for military gear and not around town holster/carry as we are accustomed to. I found a good link that tells what holster makers do provide holsters for pistols with lights/lasers. Should help you out a lot. As previously mentioned, I think most of the options will be kydex.

Sorry, I had a similar problem trying to fit my pistol (G21sf w/GTL10 Taclight) into a "real" holster. The problem is that it is the infamous "Short Frame" model with a picatinny rail. That makes it about impossible, apparently. I found a nylon one that sort of fits the bill (universal), but I'm looking for something better.
Anyhoo, Blade-Tech may be able to help you, as might Raven, but I got the best "Can-do" from Mernickle Leather. They assured me that no custom was too big or problematic.
Other private makers may be able to do the same...
Good luck and keep us posted! I for one will be interested.
