Sadly, I agree with several of the posters on this, that the 92 series is going away sometime in the not-so-distant future. I love the hammer-fired metal framed pistols, but the demand will wane and they won't remain economically feasible, except possibly as limited runs. Sure, it's basically a $600 gun, but I suspect the profit margin is way slimmer on that then on the $500 polymer guns.
Like it has been mentioned, the 1911 is not a valid comparison. Especially in the US, "everybody" wants a 1911, they continue to be the default steel gun being marketed. In the several large LGSs I have walked through (that are not big-box chains like Cabela's etc), there are lots of display counters. There are more new 1911's on display, than the entire rest of the new/used stock. This is a Beretta thread... Beretta is perhaps the only big maker I know of that doesn't have a 1911 available. And I hate to say it, but... give it time, I think they eventually make the move, too.
Sig has a zillion metal options, but they're now moving the 320. Sig reminds me of S&W, which once had so many 3rd gen variants that there's literally a decoder to help figure out what is what. ALL gone, now. Only remaining semi's- M&P, SD(Sigma), and 1911. And a new, niche 22.
CZ has a bunch of 75 variants, but they too have begun the polymer striker series.
The problem is simple, and frankly, unavoidable. There are lots of used guns around, and in guns such as the metal frames, these are great bargains. I have a Beretta 92FS, CZ 75, and Sig P226, all from the early 90s. They still run great, and if I want to replace springs (and barrel lug on the Beretta), they are now mechanically as nice as the new ones. Perhaps they get beat up... metal guns can get refinished with more options than polymer guns can. Once that is done, I then have a gun cosmetically as nice, or nicer, than the new ones. And while my pistols are testament to the continued popularity of the models, they don't make the manufacturer any money.
The Hi Power fell into this trap. They are nice pistols, that a relatively limited group of consumers like. But there are a ton of used options out there for much, much less, and 2 significant sub-groups of buyers are more inclined to get a used pistol: the person who wants just one "as example" will be happy with one for half the price and a little history; and the guys who like to upgrade guns just need a platform to begin with- why spend a lot more on something you will be swapping parts out of?
