Not in Illinois. Silencers are legal in 42 states but Illinois is not one of them. There are only eight states that currently do not allow an individual to own a silencer and if you happen to live in Illinois, then you live in one of them. Here is the shortlist of other states that do not allow you to own/possess a silencer; California, Delaware, District of Columbia, Hawaii, Illinois, Massachusetts, New York, New Jersey, and Rhode Island.
What kind of trouble can you get into if you are found to possess a silencer illegally?
From the research that I have been able to find you are potentially looking at a class 3 felony that can lead you into a probation sentence or send you away for a two to five-year prison stint. Ouch, right?
According to the summary of the Illinois House Bill 3912 below it appears that Illinois is attempting to pass/allow the use of silencers on the premises of a firing or shooting range. Did I read that right? Or, did I miss something?
