I've heard several dealers tell me that their distributors have hiked up prices and if you want a gun, you're going to have to pay that inflated price or find a better one yourself.
That depends. The big three distributors haven't gone up. However, they don't have product, so dealers might have to go to other sources to get product, resulting in higher costs.
As it is, prices on the secondary market are truly surreal, and the panic is really causing a self-fulfilling crisis. The tragedy in Connecticut happened at a time when most of the industry had gone on Christmas vacation, so manufacturing is severely reduced at the moment. Once it restarts, supply will be back out there, prices will fall, and some folks are going to regret their financial decisions.
