Dude, if I want a new Glock, I walk into one of several stores and buy one new for $500 or so. I don't need to sell my ammo to buy guns, because gun prices are the same today that they were before Covid...
Prices on guns are inflated HERE. Not at local gun stores...
If you need another kind of ammo or powder or primers or certain brass, your $500 Glock doesn’t have any bearing on the situation.
