No,
because the more guns (of any type new or older manufacture) are on the market, year after year after year, the more selection and variety for the gunsoomer.
I love shopping the previously owned firearms. You can find so much stuff of all types and vintages/ages, that is NIB unfired or barely used.
Plus people are always going bankrupt, can't pay their bills, die / an estate sale and you never know what people have in their safe, closet or underground nuclear bunker.
