Currently, they are too inaccurate to reward accurate players, and it's very inconsistent. I find that I'm within 3 in-game meters and my bullets still miss their head. (I also made sure to space out my shots so I would know that recoil wasn't a factor.) Plus, I feel that the aim assistance is a bit low on certain handcannons, but that isn't as big of a problem. I do believe handcannons should have a bit more aim assist in their respective range. The main reasons I believe handcannons should get an aim assist buff is that the movement of the game is pretty erratic, which makes it difficult to track targets even though I have good aim. Also other weapons can nock you off target by hitting you, adding more difficulty to the weapon. Plus, in a game with a medium TTD, you should have a pretty good aim assist stat, because of how long it takes to kill the target.
