The Sten Mk III, Mk II(S), Mk II and Austen Mk I all suffer from the same problem: horrible dispersion. They all have a dispersion value of 0.81, which makes them extremely inaccurate beyond 25 meters. I suggest to lower their dispersion to 0.61.
As a avid Commonwealth advocate and Commonwealth main, I am naturally inclined towards these kinds of changes…
I am also incredibly aware of my own biases. Thus, I shall wait and see how this is recieved, before I throw in my weight behind this.
In other words, I’ll go with the wisdom of the crowd on this one.
Do that and move them to BR 2 then.
The sten is incredibly easy to control and arguably is already on par with a number BR 2 weapons in terms of power.
I still use the silenced sten in BR 3 sometimes and they still do perform just fine there.
You have my backing, and that’s all you need. 
I would be careful with what degree you buff their dispersion by, their poor accuracy is one of the primary things keeping them balanced at BR1.
Looking at the data, they do seem to have a very high dispersion compared to their alternatives at BR1. I get that they need to have some drawbacks for their exceptional muzzle velocity and decent rate of fire, but 6.6 damage AND .81 dispersion is a bit much. I think a dispersion in the ~.7 range would be a fair compromise.
Probably dispersion is the reason it’s br1, no need to buff it if that means it’ll go up in BR.
Just looking at the tech tree SMGs for example, then Sten has lower damage, velocity, rate of fire, and worse dispersion than the BR2 weapons and it only has a bit better recoil. Even if the Sten’s dispersion was reduced to .71 both of the BR2 SMGs would still be solid upgrades.
Maybe a different way the Sten could be buffed is to look at its damage dropoff at 100m. I’m not sure why the Sten loses 48% of its damage at 100m with 370 muzzle velocity when the other SMGs only lose 33% at 100m with 265 muzzle velocity. I would think it would be the opposite. Different cartridge maybe? I’m not a gun expert though…
And why exactly is that a problem?
I think buffing the damage and making them similar to Lanchester’s damage would be more useful. Anyway, the Sten Mk was not known as an accurate weapon in combat.
0.000% beer matter 
I’d buff them to 0.71, a pretty standard amount for all SMGs.
Either that, or buff the damage to 6.8 and keep the dispersion the same.
Maybe you should take a look at the German counterpart, rather than at completely different weapons in the same tech tree.
You’ll find that the MP3008 has the same dispersion.
And I am highly against for every SMG to have similar or completely same dispersion. I don’t see any problem with Sten type weapons to have high dispersion. It’s not like the weapons were known for being pint point accurate.
What it needs is damage buff
it need 6.7+ damage just like other 9mms
In general I agree, but maybe at least 0.70 like on MP40?
No
It really isn’t tho because of the low damage. If the damage is increased to 6.8 at 10m which is pretty much standard damage for 9mm SMG along with the dispersion buff then maybe. But then you have to ask yourself a question that why would you even uses Sten gun instead of Lanchester which is pretty much better in every way if you make Sten gun BR 2.
