Reuters reporters went to gun shows in Pennsylvania, Missouri and Texas, and found long lines to get in the door, crowds around the dealer booths, a rush to buy assault weapons even at higher prices and some dealers selling out. 

The busiest table at the R.K. Gun & Knife show at an exposition center near the Kansas City, Missouri airport was offering assault weapons near the entrance.

 

West Plains, Missouri dealer Keith's Guns sold out of about 20 AR-15 style assault rifles in a little over an hour, owner Keith Gray said.

 

An AR-15 type assault weapon was among the guns authorities believe suspect Adam Lanza stole from his mother to use in the massacre of 20 school children and six adults at a Newtown, Connecticut elementary school on December 14.
