Resolved to my satisfaction.
I spoke with James today - all set. Lesson learned....be sure to call any vendor without feedback on AR15.com to verify a business and assure yourself that your expectations will be met. Mine were not, so after a follow up phone call this afternoon things were clarified and everything is all set now.
The problem is that aside from AR15.com, were vendors are expected to stay on top of online correspondance, other folks don't know the assumed protocol and in lieu of that...the customer (ie Hokie) can get pretty fired up.
Pending the arrival of my slide, I will leave XD-HS2000.com some feedback and recommendations for others who need XD work done by a qualified gunsmith.
