It is overpowered because:.
1) more damage, even if it's 1
2) It's more accurate. Sure you can bring me the config stats of it?
= it has less bullet spread. Put wallmark 'long' on, shoot against a wall from 10 metres. And compare it with usual smg.
but by Playing with I know it's sten-like accuracy. But sten is even more accurate.
3) 40 bullets in 1 round.

ps: I like that gun. Not that I want to see it removed! that wasn't my intention. It's just the best gun in whole et.

But this wasn't what this topic is about.
That gun is bugged for tsp.
Or it isn't bugged. Therefore it doesn't belong in the category smg, where headshots do count for your tsp.

Any tb'er can respond on this?
