Remember, firearms are badass.

If I might chime in...

Perhaps the PCs don't want to deal with the high loading times of early firearms? They want to be able to fire their guns once every second or third combat round, like a bow or light crossbow, instead of once or twice every minute, like reality.

In which case, that should be a personal preference of the characters to not use the new-fangled fighting machines, not a setting fiat.

Remember that gunpowder artillery was used in the Hundred Years War. Joan of Arc, one of the late medieval times' greatest generals, used and fought against them against England... and that was in the 1200s, IIRC. TL4 didn't officially start until 1450.

What I think the PCs want is something akin to D&D: a pseudo-Renaissance-era setting with Crusades-era combat. Might I suggest that the OP use a either a High Medieval, mature TL3 (circa 1000-1200 AD) setting, or a fully-TL4 Renaissance (1450-1600) setting, complete with firearms and cannon. Either will work.

If the OP wants a mature TL4 Renaissance-era setting, I'd be glad to send him my world setting.
