It was on the TexasGunbroker website, and I don't thin it was a joke. Lots of - shall we say, uniformed folks on there. Also saw a Glock for sale the ad said was in 45MM.
I have one made by Harrington Richardson. He was quite busy for many years. I have to admit that his stuff looks a lot like the items made by that other guy, Iver Johnson, though.
I like the "rare Bearcat" ads that say that it has an engraved cylinder. The one I am looking for is the one without the engraved cylinder...from the factory.
