Chris,
Here's a couple I didn't see on your list:
http://www.bluelineleather.com
http://www.jjheroldholsters.com
(I'll go thru my bookmarks when I get a chance and see if I have any others)
Went thru my bookmarks and these are the one's I have that don't seem to be on your list:
http://www.concealedcarry.com/
http://www.concealedcarryoutfitters.com/index.htm
http://www.dmbullardleather.com (I think this used to be dmbleatherworks)
http://www.tacpro.com/index.htm
I probably have others, but I have my bookmarks broken down a little differently (makers/manufacturers vs resellers)
If I see any others I'll add them in a seperate post at the end of this thread.
