I just bought a Z3 i got it last month.I talked to a shipping rep from surefire about one of my orders for some Z3 accessories and she dropped some info on me about why shipping stopped. Their shipping has been put on hold for inventory contol at Pk's headquarters until jan 6th. Those models have been discontinued and taken off the site for the 2003 remodeling they are doing to the site. I feel a clearence sale coming on too.
