Anyone porting/tuning 3.5" Prodigy?

Considering getting a 3.5" Prodigy and wondering who is porting and tuning them. I've searched, and most of what I'm finding is for the 4.25" or the 5", but no one specifically mentions the 3.5". Yes, I know about the Bul, GP Arms and Alpha Foxtrot, aesthetically, I like the Prodigy more than the others. Thanks!
