Most weapons could use just some slight tweaking to make them feel better.
Like the Halt. A bit more UMF to it, or accuracy.
Same as the Tenderizer. It shoots good, it kills good, but something is missing.
The SMGs are all over the place and only the totally-not-a-battle-rifle-carbine Reprimand works best. Could do with a smeg that has a normal rate of fire of around 700-900 RPM though.
Maybe sweden is afraid of a space MP5 or space Uzi. But I barely if ever can think of a situation where I go "man i sure do wish my weapon was one-handed right about now"
