I believe they are out of production...made by CZ for Springfield Armory.
They come in blued, or stainless...the latter being more desirable.
They also come in .22LR/.410 shotgun, as well as .22 Hornet / .410.
I had a .22Hornet model, which I traded for one in stainless and .22LR.
They are fun to shoot, not the greatest trigger, and likely to appreciate in value.
They come up on the EE here from time to time, but never last long.
Good luck in finding one!
