"Mileage varies depending on driver"
I have dealt with both Mark and Ken from Specialized Armament. Coincidentally, they came highly recommended by folks from Colt. Both ex-military and great people. Very trustworthy and honorable.
Usually, the best way to contact them is by phone. They run a small, quality operation. So sometimes Mark will be out bringing in the UPS shipments, in the shop or some other mundane duty and can't answer the phone. That's just how they roll.
Oh, and they will often work with you on price (within reason) and offer an LEO discount.
