I think you mean you need a Grip for a TMX Special. As long as you have the correct grip from Vern Brown, any PFS stock will work for you. Call Vern and see if he has what you need. His cell is 719-250-7727 and he calls people back if they leave a voice mail.
I have a short model that is like new, it is the new style, and adjusts from 12 1/2" to about 14 1/2" LOP. it has a wood cheek piece. The grip I have is for a TM-1, Right hand, I think this is the same as your TMX Special [ I would check w
with Vern on this].
I also have grips for Ljutic RH, if anyone is interested Price $900 shipped. George Olsen 516-446-2482
