Most large chain-stores or sporting goods outlets did not/will not jack-up the price on new guns or even ammo. (Though I have heard a couple of stories concerning Cabella's which contradicts that.) Price increases will only roll-out as/if the price of the gun goes up from the manufacturer. You just have to be there to get what is available. I have been purchasing ammo at practically pre-panic prices, but you never know what the store will receive or when. With a bit of detective work, you can buy ammo at decent prices, even 22. Like others, I have not observed new gun prices escalating to any great degree. Again, like others noted...the price of used guns have drastically increased on sites like Gunpoker or Gunsamerica. You could purchase a used j-frame 38 in the $450-$500 range a couple of months ago. Now, one can scarcely be found for a price close to that and when you do see one, it will be closer to $600 or more. It also seems to me to be model and caliber specific. Just about anything in 9MM or 380 will sell at about any asking price. Next to the AR-15, Mini-14 and like carbines (of which prices are now moderating a bit), people seem to want light-weight carry guns. 380 and 9MM being the most popular calibers.
Ammo prices seem to be moderating a bit as well. My Brownells flier this past week had most popular center-fire handgun ammo at close to pre-panic prices, BUT NO 22 at all....period.
Sellers are dragging guns out of the back of safes they have been unable (or unwilling) to sell but are cashing-in on current demand and getting much higher prices for the "right" used handgun.
