Expensive club - CAA Sig Sauer P320 Pistol Micro Conversion Kit

I have a P320 Carry
***DOES NOT WORK WITH WILSON COMBAT GRIP
***DOES NOT WORK WITH X CARRY GRIP
***DOES NOT WORK WITH SLIDE WITH TRUGLO TFX PRO SIGHTS
Looks like it ONLY works with older/original frame/slide/sights.
Could not get so-called extraction buttons to lock the rail on the grip frame. Looking inside with a light I could see the crossbar that the buttons would drop when pressed. But mine never would lock. Looking with a flashlight I could see the barrel lined up with the MCK barrel shroud and the pistol was all the way forward as the front of the trigger guard was hitting the frame of the MCK.
And even though it was all the way forward, the hatch/door would not clear the very last bit of the grips beavertail.
So, I'll find someone that I can sell it to at some time in the future. Sad, 'cause it do look kool!
If I get an original slide/sights I'll give it a try.
