While I was out of town, it appears that Heizer has posted their first video on the DOUBLETAP. They've also added many more details about the pistol. Very notable features are interchangeable barrels and the option of Aluminum or Titanium frame. Porting is shown as an option for those that would rather skip it. The MSRPs have also been added to the Heizer website. First quarter 2012 is just around the corner.
Rather than create a new blog for this update, I'm just going to edit my previous blog and add this video link to Ray Kohout, the inventor of the DoubleTap explaining and demonstrating his new invention. It does look pretty sweet.
