That's the way it goes, I guess
When I got my Beretta 87 Cheetah Standard (I didn't want the target model), I was lucky to find one NIB. It's no longer listed in their catalog.
Come to think of it, only one of my firearms is still in production, the Marlin 1894C. The rest have all been discontinued, but they're still good shooters, and the values for them keep heading northward.
Keep your eyes open, and I'll bet you can still find a NIB 92FS. That's a great handgun.
