How advanced is firearms technology? Musket-level, I would assume, maybe wheel-lock if they're really dedicated to this whole "shoot things" business.

If it's Renaissance-era weaponry then you should Imagine flintlock and Snaplock Muskets, Though i'd imagine they coexisted among their predecessor the arquebus. So not the most primitive of firearms but they would still take a while to load and wouldn't really be all that accurate. They'd also have an Arch nemesis in water, when the powder inside the gun is wet you can't ignite it which means you can't shoot.

Also remember, soldiers in the Renaissance still wore plate armor and not all guns were able to pierce the chest plate of an armor. Although i must personally admit that I don't really know how Varromere imagines armor in his world.
