As Explained in another thred on here all weapons have a maximum and minimum damage value. Weapons do their max damage up until a certain distance when the damage begins to decrease and eventually levels out at the min damage value. Silencers will cause this falloff to occur earlier, and thus do less damage at longer ranges.

After Reading this i though it a good idea to serch the web and get the damage stats for all guns in detail for all of ttg to see in one easy place.
