I can't seem to find much in the core rules that addresses firearms vs. melee weapons in combat. Obviously, at range guns win every time.
All I can find is those with fire-arms do not get the (+30)% point blank range bonus while engaged in melee. Which means if you are using an autofire firearm against someone who is trying to hit you with a chainsword, you are probably going to do far more damage to them.
Is anyone else aware of any other rules?
