I'm sure at some point someone will make them. But it's not a great selling point if your new light, however good it might be, doesn't fit any current holsters. Just my thoughts from a business perspective.
Are you sure of that? They intend that it will fit Safariland duty holsters 6000 and 7000 series that accommodate the X300 and TLR-1, but I've never read that they're intending to match the X300 profile. Much of the same stuff was spread around ahead of the PL-350 launch and it was simply not the case (and Modlite never said it was.)
I believe you are correct. I went back and looked through Cloud's IG and it only notes compatibility with the Safariland duty holsters that fit X300 and TLR1. I must have misinterpreted that as being broadly compatible across the board.
Hopefully it will be more broadly compatible.
Is there any update as to when this light will be available?
