.50 BMG Handgun.

I stumbled upon this earlier today. It's a few years old but still worth a look. Too bad it didn't go into production.

I saw a large "handgun" in 50BMG back in 1995 time frame. That guy who was in Utah but moved to Arizona and was busted a few times for making unregistered firearms and sold plans for 50BMG rifle which he claims LAR stole from him, etc -- forget his name -- showed it to me (in photograph form). He was interested in advertising his sabots he was selling at the time online and I was talking with him about that aspect when he showed me all his 50 stuff. Was bigger than this one but still a "handgun"

Never was produced either and I would not have wanted to be around to see it shot
