Holster for Sig P220 Combat TB w/ light

I finally bought a Sig P220 Combat TB yesterday, and I picked up a holster to go with it. But the pistol didn't fit in the holster, even though it claimed guns with rails would snug right in there.

After an hour or two of looking around online I can't seem to find a holster, not with any certainty anyway. What's more, I'm very probably going to add a laser/light combo to it. So I'd like a holster which can accommodate that as well. I don't particularly care about materials; leather is fine, synthetic is OK. As long as it can attach to a belt I'll be happy. I saw one "universal MOLLE" type, but I have no idea if you can attach it to your belt.

Oh, one other item: if it happens to have an open end so that I don't need to remove the Gemtech Blackside suppressor every time I want to holster it, that would be a definite bonus.

Would anyone have any ideas? I appreciate it in advance...

Thanks for the info!

I went and looked at the 6004, and it's pretty much what I'd like to get. But the 220 Combat TB has a 5 inch barrel (the normal 220 has a 4.4 inch barrel). That extra .6 inches is the threaded part. Also, from the measurements I've been able to find, the rails on the 220 Combat are wider than the 220R (which is the only 220 I've been able to find mention of on holster manufacturer's web sites).

Over the weekend I found a generic nylon holster that fits so-so, but without a light. It'll do for a while. I think I might find a leather guy here in town and see about having a holster made custom. I can have it shaped such that it'll fit with a light mounted, and then have it open-ended so that if I happen to have the suppressor on it I can still holster it.

The search continues...

What USP said, John. I bought a Serpa made for the 220R figuring that it was the same size as the 220 Combat. No dice.

I'm going to try the Safariland. If that doesn't fit, I'll find a custom leather guy.
