10m 5 shot range for MX9 would be good. Still wouldnt outgun the spitfire, but would at least be a consistently good close range weapon.

6m 5 shot for the GKS would help is a lot in close range, the 3m 5 shot is just too short to be in anyway reliable when fighting im close quarters.

I think the Cordite should have a 6m 5 shkt as well for the same reason, and the operator mod should cooldown slightly faster too.

IMO the Spitfire is fine, it absolutely destroys everything with the Wildfire mod. Maybe a slight decrease to its base reload speed, as it is much longer than the rest of the SMGs.

Making the MX9 a 10m 5 shot could make the Saug a little weak though, I think increased base handling stats could probably account for that though.

I also think some of the ARs (VAPR, KN) need an increased fire rate, with the tradeoff of a lot more recoil. ARs shouldnt be basically lazer beams, they should have some kick, but the kick should be very predictable. Right now the VAPR has a little bit of kick, but its extremely unpredictable compared to the rest of the ARs. Makes it a little bit bad at range since it jumps side to side randomly.
