I was hoping when I saw this thread back up, that one had been spotted in the wild. I am still looking.
Hickock45 just did a review of the one supplied to him by Bud's Guns. You may want to check slickguns on a daily basis to see who has them.
Side note: I'm not sure if Hickock45 was just off his long game or the sights of the Cobra were off, but he could not hit anything at distance with the Cobra. I have seen other videos where he shot many short barreled pistols and did just fine. My guess is that the fixed sights of the Cobra gave it a left of center POI that just gets more exaggerated with distance... All of his shots had a leftward bias.
