Probably old news to everyone, but I noticed that the 9mm version of the LCR is for real and is on the Ruger site.
Like the LCR 357, the LCR 9mm has a stainless steel frame. (The 38 and 22 version have Aluminum alloy frames).
9MM is one of the most readily available rounds, and lots of good SD ammo exists.
And practice/plinking ammo is cheaper than everything except 22lr.
It's not on the California approved list yet, but there should be no problem as the other LCR models meet the criteria.
As soon as I can, I plan to order one.
