My guess is poor sales. Beretta 92 compacts don't sell nearly as well as the full size, either.
In the mid-'80s my employer was issuing full-size Berettas. When the Beretta 92C came on the scene, we all lusted for one but they were unobtainable, even for our employer. We were told everyone in the world wanted one. They got sponged up the moment they left the factory. I quit thinking about them.
Then I was on duty in Tunis and was whining about being unable to get a Compact. My Egyptian colleague reached under his coat and pulled out a Taurus PT92C and made me a very good price. With 2 mags. Up until then I had only really bad experiences with Taurus and wanted to say "No", but between the bargain price and the fact that he was taking a risk selling me what was most certainly illegal for him to own, I bought it to do him a favor. (I'm such a caring person . . ..)
It turned out to be 100% reliable with hot European ammo, and very accurate. I kept it through retirement. Of course it looks very like the one in your pictures, except that mine has much darker, and slick, grip panels.
After retiring I saw a Beretta 92C and bought it just because. It of course has the safety on the slide, while the Taurus' is on the frame. Much better. Nicer-looking, too.
