Tru-Thread Turkey Choke Options?

[Ridge Rooster]

I am having a Benelli M2 20ga barrel shortened and most likely will be re-threaded for Tru-Threads.

What options are out there?  I have heard that Indian Creek (My go to option) will occasionally thread a choke for Tru-threads but I have asked them in the past and they really don't give a good answer on availability.  I know they are busy with more common thread options so I understand them not wanting to stop production and make a Tru-Threaded choke.

Curious what options are out there?

Sumtoy most always has them. Carlson also.
