WHAT DOES B&T INDUSTRIES 9MM HANDGUN DEALS MEAN?

I at the moment only have Miroku models (twelve gauge mag is still my go-to waterfowl gun; and it has worked in all sorts of weather all the way down to -2 F when many other excellent guns while in the blind or boat get squirrelly.why can it be so difficult to find a great quality repro M1 at somewhere within the $five hundred-seven hundred range?
