Kobold Avenger,
problem is, things are *never* static.
Once you have the tech for those...it will evolve as other techs improve.
A rifled barrel percussion rifle is very accurate, note the buffalo guns.
In my games, things change over time...
Way I look at it, we 21st century humans cannot really comprehend "alien", by this I mean, anything not like our world and time. We're "locked" into our world view.
In my homebrew setting, a quasi-Roman empire has legions fitted with adamantine weapons/armour, mined over millenia by condemend slaves. Adamantine lasts for many many thousands of years of use, each piece is numbered and thefts always recovered and drastically punished.
This gave the empire a massive advantage, along with organizing a military wizard schooling and integration system, so each century would have a 5+ clerics and 1 or 2 wizards.
So, mixing our world history, with some D&D stuff, things coudl turn out, odd
In my settign the nation who have magical-pistol usign wizards is sort of like early 19th century USA, traders extraordinaire, where magic and odd technoglogy (not our tech, more like gnomish stuff that works!)
