Do an internet search, when you run across a place that shows out of stock (OOS) some of them have a "button" you can click on to leave them your e-mail address and they will e-mail you when they come in stock.
When I got mine I had just come in from mowing/trimming the yard, saw the e-mail, got to the website and ordered the P01 (black one, like you want). Then I went to the CZ Forum to start a thread to let others know that vendor had several in stock. I typed the title of the thread, a short bit of text and went back to the vendor web site to click on it for a link to insert in the CZ Forum thread - and they were out of stock that quick.
The e-mail was all of 20 minutes old when I read it and it took me maybe 5 or 6 minutes to get my wallet, do the order and get the message telling me they would e-mail me with the order number/confirmation. Had me worried for a bit till I got the confirmation.
They go quick. Have your money/credit card ready and set up on vendor websites to get that e-mal when they get some in stock.
And what's wrong with Urban Gray??? Fraternal twins, not identical twins. Both have Olight mini's on them now.
