Actaea

So, does it grant this skill? But a cut-down version, without "grenades and other stuff"? And does it still require 5 skill points to get the full version?

Yes. You can use weapons without the skill (just like grenades), but there will be a penalty to accuracy, etc. (and in the case of grenades, you might even blow yourself up).
