I just gave EFK a call and they are backed up! The election has overwhelmed them with orders. It's a small family business so they working double overtime just to keep up. They're trying to keep their prices down and maintain a steady production run. Unfortunately this means they'll be cutting back on everything that isn't common. They'll still support CZ, however only the 9mm. I'm sure its possible to negotiate something with them if someone wants a .45 or some other conversion. But they won't boot other customers out of line even if someone is willing to pay more. So they've got a lot of integrity over there.
It'll be a few more weeks till my barrel arrives.
