From Farmer Frank's blog - It has 2 barrels, 2 slides, 2 triggers, 2 magazines, but only 1 SEAR! One trigger doesn't work. You select which side you want the sear on and that's the trigger that operates this thing. The hammers while looking like 2 hammers are actually a single hammer, that operate off the single sear.

The AF2011-A1 ("Twenty Eleven" for aficionados) can be ordered either with 2 independent triggers and one sear group (left or right, with user-interchangeability for right or left operations) or with 2 triggers permanently joined and the choice of 1 or 2 sear groups.It looks like it doesn't matter whether you get 2 sears or one sear or two triggers or one trigger, it all comes out the same ... everything does go bang with one pull. Have no idea why you would want independent sears that were always both actuated ...unless they are trying to build redundancy...
Honestly, no matter how you try to figure out what the goal is, it is still doesn't wash.
The only ting it does do is deliver an automatic double tap every time you pull the trigger. Might be effective at stopping a bad guy, but can you imagine the smile the prosecutor will have showing the jury those two great big barrels?
