Just in case one .45 ACP 1911 wasn’t enough:
As much as a photoshop joke that this seems, This 2011 by Arsenal Firearms is the real deal. I’m sure it won’t be cheap. My first thoughts (aside from “are you kidding me?”) was that it will constitute as a “Machine Gun” by the ATF and be non-transferable to civilians, but they also have the option of independent trigger sears. Practical – no. But I’m positive you will be seeing it in wielded by some hollywood villan in a corny action movie soon enough.
