Supressors do not change the velocity of a bullet. They only do that in movies and video games.
What they do:
Reduce felt recoil
reduce or eliminate muzzle climb
Reduce sound signature
well designed ones increase accuracy
Increase gas pressure in gas operated firearms
Reduce slide energy in delayed blow back operated pistols
Due to the reduced recoil energy most handguns need a nielsen device that attaches to the barrel then to the suppressor to get it to run. Any firearm that you want to suppress needs some sort of threading even integral suppressed ones
