I had the same problem last year trying to find a concealed holster for my then-new 96 Brig. Here's who has one specifically for this gun:

I am pretty sure I bought directly from them, but Gunner's Alley carries this line, and based on my experience with them last week, they have all my business for stuff I cannot get quickly from my local gun store.
Here's my review, but with an important caveat: I almost never carry this gun concealed. I bout a SW99 .40 compact soon after and it is my daily carry piece. But I love the Brigadier. Just too big for me to carry every day, especially in the summer, and I like to keep things consistent in this department.
The holster is definately made for the Brig. It has a pretty large "tunnel" for the front site, although there is still a bit of interference from time to time that scrapes a minute amount of Kydex off. I suspect if I carried it regularly it would work itself in a bit.
Build quality is outstanding. Far superior to my Fobus paddle holster. It has the sweat/shirt guard. Retention is perfect. And it is a very comfotable carry. Its just the gun thats too big!
If I can figure out how to post a pic of here I will, with the gun in and out.
Good luck.
