They bought out the Galyans that used to be in Fairfax, VA. Galyans sold everything, including handguns. When they changed to Dick's, they got rid of the handguns, and replaced most of the gun supplies (which included holsters, magazines, etc.) with a bunch of airsoft and paintball crap.
They do have good prices on ammo during their sales, and they do sell some "evil" long guns, including a desert camo mossberg with extended mag tube.
