As long as they do a job and people like them: The basic job of a gun is to shoot something. A gun needs to be relatively simple and reliable, able to be ignored a lot and ready at a moment's notice. While a lot of fancy guns used exclusively for war will be outmoded as soon as a better gun is made, for self-defense people still use revolvers and automatics ...

Just how "identifiable" should they be? I think it is improbable that the military or ordinary civilian shooters would use weapons that are actually 200 years old. Some collectors, maybe, but those who actually shoot their genuine antiques would be a small subgroup within a small niche. But just how different can a modern weapon be and still ...

Give it an in-story reason What has happened in the past 100+ years? There are several reasons that firearms development might focus on the early 21st century firearms. No need Maybe the society doesn't need anything more advanced. If the biggest threats are lightly armored opponents, there's no need to throw more resources at firearms development. Gun ...

Unless some insane breakthrough in energy storage density occurs, it'll still be cheap and effective enough to use gunpowder powered weapons. The same basic weapon layout will still be functional enough, although I am ...

As a result, why change the design of ...

All of the supplies needed to operate such weaponry is readily available, even to the general public (gunpowder, pellets, paper/cloth, fuses). Technological advancements have made firearms faster, easier,...

If firearms designed 200+ years before are still in use by the military of any Country (guerrilla forces are going to face different priorities) it would mean at least one of the following (but not necessarily all): A - general tech development has slowed down. This may happen for economic reasons. R&D of new weapon systems is extremely expensive. That ...

However, I still want to feature firearms that are identifiable in the modern day, like the AKM, M16, LSAT, AA-12 etc. A lot depends on your reason for wanting them to be identifiable in that way. If it's to ground your future world in today's reality, a tried-and-true way to do that is to use familiar-sounding names but invented models, perhaps even ...
