Man, even people living in Washington state can be courteous of their neighbors and use suppressors. House Bill 1016 was officially signed into law which legalized the use of suppressors within the state and put Washington one step ahead of Minnesota in that regard. The following paragraph sums up why suppressors should not only be legal in every state but should also be removed for the list of firearms and firearm accessories that are regulated by the National Firearms Act:
Anyone who has ever fired a gun knows that gunfire is loud. It can cause immediate and permanent hearing loss. While suppressors do not eliminate the sound of a firearm, they do reduce the muzzle report of the gun much in the same way that a muffler reduces exhaust noise from a car or truck. There are many benefits to suppressors: they can increase accuracy, they make shooting more enjoyable by lessening felt recoil and reducing muzzle blast, they protect shooters’ hearing, and they help to reduce noise complaints from neighbors.
If you live near a gun range and find the noise annoying you should be advocating for the legalization of suppressors. I would love to see this happen here but alas I think it may be a while.
