People who buy guns come in a few flavors, but many "hoard" them, meaning they oveall add to their collection and don't subtract.
In that respect, guns are not like other 'durable' goods. Most people only have 1 couch, 1 refrigerator, 1 stove, 1 set of washer and dryer, etc. Most folks don't buy extra durables for fun, gifts, pleasure, to collect, etc. But people add guns to their collection.
With population increasing significantly, and the predictable 'civil unrest' that we are almost certainly to see in the near future (won't go into my theories), gun sales are going to continue to stay steady or go up, not down...
That means that prices will not be going down across the board...
