My Kestrel holster took 5 business days to receive, ordered mine thru EBay. Not certain on the warranty contact them to ask.
I ordered the Carbon Fiber in FDE. (flat dark earth)
Ordered my direct from Krestrel web site. Mine is to plain Amish black. You gave a good description of the retention function, I just wanted to make sure the pistol does not go sliding out at the wrong time.
