Yes and No. They are illegal unless you get a approval from ATF. Silencers are considered a "title II" weapon or NFA type weapon (read below). All NFA items must be registered with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). Private owners wishing to purchase an NFA item must obtain permission from the ATF, obtain a signature from the county sheriff or city or town chief of police (not necessarily permission), pass an extensive background check to include submitting a photograph and finger prints, fully register the firearm, receive ATF written permission before moving the firearm across state lines, and pay a tax. The request to transfer ownership of an NFA item is made on an ATF Form 4.
check with the prosecutor's office
Unfortunately yes. But there are ways around it.
Depends on who is using them and for what.
if a gun has a threaded barrel, (required for a silencer) it is classified as an "assault weapon" and is illegal in California.
yes silencers are illegal in montana
No, you have to have a tax stamp from the ATF... but with that stamp it is 100% legal.
Depending on who you are, no.
That is an extremely difficult question to answer with any accuracy, but the basic answer is, just like anything else that is illegal, somebody in the legislature doesn't think you should own one, so they passed a law saying you can't.
Silencers are illegal in SOME states for the general public, but only a few. See link below
Yes
No. In Florida, you must have the gun concealed. There is not an exception for Tennessee residents.
