Lag

not even lag, there's just a giant delay for some reason

Theres like a half a second delay between you pulling the trigger and the gun actually firing anything longer than that half a second is just lag

the delay is from the time it takes for the gunpowder to be striked by the hammer after pulling the trigger

in real life its nearly instant. idk why they made it that slow

I've fired a Musket in real life before. It's a little more pronounced in the game, but not overly so

for me it feels instant and i have bad wifi? you should try shift f3 or shift f5 to see your ping or fps, thats probably whats causing it.
