Combat always degrades into a sprint towards with the blunderbuss then bunny hoppin around like mad while they reload to repeat.
The reload time could be increased
The one shot potential could be removed and make it a 2 shot kill even at close range
The reload could be interrupted of the player moves or jumps whilst in the reload animation.
A combination of, one of or all of these ideas would help make person to person combat more of a fight and less of a sprint/bang afair.
It's also of note that PC uses with a mouse have it far easier to twitch aim quickly with the blunderbuss up close to get that one hit kill but the precision a mouse gives over a controller will always be an issue across any game.
