I have one of the xts models you are searching for (blue and chrome). It is fully functional and ready for field use. I am an airsmith and went through it when I purchased it. Necessary seals were replaced, it was cleaned and lubricated.
If you are interested, I can send you photos or post in another reply thread.
I'm seeking a pistol such as a delta 68 or similar. You can also make me an offer if you are interested.
Thank you for your time.
