I recently purchased a pistol that is sold in Canada so it is obviously under 500 fps. However, I found messing around with it, that there is a very simple way to change this velocity in a drastic way. What are the requirements for this? How hard does it need to be (this is simply screwing a screw in a bit). I currently have it set for under 500fps and am trying to figure out how to keep it like that and be legal as well.
