No, years of cumulative recoil are not making you see double (well, maybe it is, but then you would see a 1911 with four barrels). This is a double-barreled 1911. It not only exists in the video below, it was recently displayed at IWA, the European SHOT Show, by Arsenal Fireams of Italy.
It has what looks like a one-piece double slide, a double hammer, and, apparently, two triggers, either of which trips the hammer. The magazine, as you see in the video, seems to be double, too.
If you had very large hands, didn’t mind recoil, and believed that anything worth shooting was worth shooting twice, this would be your gun.
Otherwise outside of “John Woo action movie prop,” I don’t know what future I see for the 2011-A1. I would like to shoot one once, though.
I cannot wait to read your reactions.
