There are less than a million legal gun mufflers/silencers/suppressors in the United States.
Those numbers are just scratching the surface.
There are about 300-350 million firearms in the United States.
Realistically, there should be upwards of a hundred million suppressors in the peoples hands.
They should be purchased over the counter in hardware stores.
The over regulation of gun mufflers and the millions who have lost hearing as a result are a national disgrace. It is one of the worst government health caused disasters in U.S. history.
My mistake. I read it as sales when the numbers actually represent total licensed silencers.
I once talked to a guy who went to New Zealand on a hunt. He showed me pictures of a cheap cardboard box containing a 22 suppressor hanging in a store display, with a sticker for 8.95 New Zealand moneys. He said it was considered being polite to your neighbors to have one on every gun.
