Yes, I know it's suppressor, but in the show they called it silencer. An Idaho leo said on camera that silencers are illegal because it messes with the rifling marks on the fired bullet, which I disagree with as the reason, but the statement from a forensics guy on the episode really made me baffled. He said depending on how the silencer is turned when mounted, it puts its own marks on the bullet. I find this difficult to believe, in that it is my understanding that if the silencer/suppressor touches the bullet, the trajectory would be changed and thus POI would change, which is not something the shooter would want. So, you guys who use them, is the show simply full of bovine excrement, as usual on tv?
