AFAIK, the green zombie grips by Hogue were only made in the standard Hogue configuration, that is: with an open back strap.
The Hogue grips for the X-frames had a covered back strap and a recoil absorbing insert for the web of the hand.
Since the X-frame grip-frame is a K/L configuration, you can use the standard grips, but you will pay a penalty in felt recoil.
The recoil absorbing X-frame grips currently are available in black only. Previously, you could get them in yellow or orange (made for the emergency kits) and I remember seeing them in FDE or military green at the SHOT show several years ago, but have never seen them in the wild in that color.
S&W had the exclusive on the X-frame recoil absorbing grips up until recently, but my understanding is that they are now available directly from Hogue.

Good luck in your search.
