After many attempts of searching and failing, only leading back to posts with 'key words' I seen a few posts, about a flash light mod? I'm not sure if this is what I'm thinking it is, though could someone direct me in the right direction?

Thanks

If you press "H" with your pistol out, then you get a flashlight attachment. I also know that a modder is working on a flashlight model, but that hasn't been released yet.
