Rereading the copy the LM4 may be a semi-automatic, but I'm not sure.
They offer an over/under double action derringer in .38 Special which is not vaporware, and claim to be offering it in .40 S & W as well. Also a remake of the High Standard .22mag over/under double action derringer.

The LM4 was a manually operated repeater. The user had to rack the slide between shots.
I've never heard of a COP in anything but .357 Magnum.
