Remington’s parent company recently reported a 34 percent quarterly sales gain, while Connecticut-based Sturm, Ruger & Co. saw transactions soar nearly 50 percent. Sturm, Ruger even stopped taking orders for two months to catch up on back orders.

All told, background checks for new gun purchases — the best gauge of overall U.S. weapons sales — rose 14.4 percent in 2011 to 10.8 million, according to the National Shooting Sports Foundation.

“There’s no one reason that explains all of the increase, but what’s been called ‘The Obama Factor’ undoubtedly is an important part of it,” said Lawrence Keane, a senior vice president at the foundation.
