This is tough with a 9mm can. I have a 3-lug on one of my 9mm AR's and use a Gemtech Multimount.
IMHO, 3 lug is the way to go, especially since . Would suggest using Rocksett to make sure the adapter stays in place (this is a common failure). If you are feeling like a tactical operator operating, you can get FHs and brakes for 3 lug.
As for a particular vendor, In Lead We Trust makes a VERY nice Navy-style adapter that works well with my Octane 9 and AAC FH. It is also nicely priced for what you get. The price differential over the cheaper ones is low enough that I think it's hard to justify going any other way, but YMMV.
