I somehow find myself doubting every firearm manufacturer that sells in the US got together and agreed to all raise their prices 10%. Will some prices go up? Probably. Will some go down? Probably. Will it still come down to the variation based on individual gun shop markup based on their cost and their desired profit margin? Definitely.
What he said to you was to try to get you to buy a gun then and there. Go back in a couple weeks, and bet he'll try something else to try to get you to buy a gun right away too. Maybe the UN Gun Ban, or the Obama Gun ban, or the new secret law that was snuck through congress and signed in the middle of the night yesterday by Obama that says that all guns sold in THREE weeks will be registered in a super secret database by use of RFID cards that are hidden in the guns, and that their locations will all be secretly tracked by satallite so that in a year the ATF can swoop in in their helicopters and confiscate all the guns in the country and arrest the owners, so buy now before they get registered!
See where I'm going with this?
