It looks like a 1911-esque polymer frame, which I've been waiting for someone to make. Unfortunately, they lengthened the grip, which is the best feature about the CombatMaster. At least they got the rear sight in the right place.
I don't know if you knew this, but "New Detonics" was the name of the company during the Phoenix years. Here's hoping that they make some good business decisions, and that Detonics is around a while this time.
