Gun prices are at or near rock bottom for these times. Production was high in the run-up to an election everyone "knew" was going to go a different way. That led to a pretty-saturated market, especially of AR-type rifles.
As mentioned above, CC-type handguns abound, and are super-affordable. No real "comebacks" in the steel-framed world, though CZ seems to be doing their best.
Mil-surp guns seem to be holding steady, if not ticking upwards. Import tariffs have driven up more sharply the prices on anything Russian, as well as on some AK-types from other Eastern-Bloc countries. While AR prices have flattened, especially on "entry-level" models, AK prices have risen.
During the .22LR shortage of several years ago, I was finding some pretty good deals on used guns in that caliber. That seems to have run its course now, as .22LR ammo has been widely-available for some time now (though it still runs about ten percent higher in some cases than prior to 2013.)
