I ordered one a few weeks or a month or so ago, and was told they were back-ordered. I left the order standing, and it arrived last Friday. So mine only took about a month.
Dunno why LPS has been so long, unless Surefire is just now catching up with shipments to their dealers, and I happened to catch one as it was transiting through their warehouse. Give Surefire a call and see if they have any in stock, and then call LPS and see what the buzz is on their end.
