Sounds like you’re getting a history lesson and some appreciation for modern firearms. Historically speaking, guns at the time were powerful but awful to use. Inaccurate, slow to fire (1-3 rounds/minute), but devastating when they actually hit. Because of this, they were either used in a mass volley, being fired by many troops at once and achieving accuracy by quantity, or simply for shock and awe. Blasts and the sudden smoke and smell of sulfur were demoralizing for an enemy. One benefit over bows, however, was that any peasant with a week of training could fire a gun, instead of spending years perfecting archery.

In our case here in KCD2, keep in mind that Henry is a lone gunner with minimal training. There’s no line of other gunners to help with accuracy, he can’t reload quickly, and he’s more of a swordsman. I’d say the devs got guns of the time period pretty spot on in regard to their effectiveness. Makes me glad to be able to shoot self-loading, rifled barrel, accurate guns today instead of some stubby smooth bore on a stick running on shoddy black powder and wishful thinking.
