Does the nra really have 5 million members?

jan 2013, mother jones: In 2008, Josh Sugarmann, executive director of the pro-gun control Violence Policy Center, came across more evidence of the NRA's fuzzy math. He pointed to a piece of junk mail that the NRA's treasurer had sent to members peddling a specialized insurance plan aimed at gun owners. The pitch stated that "with about 3 million NRA Members 'on our side of the table,' we negotiated a bargain price." Sugarmann has an intriguing theory why this number may be more credible than the one that the NRA routinely gives the press: The underwriter for the insurance plan was in California, where making "untrue, deceptive, or misleading" statements in insurance materials is outlawed.

Last week, the NRA claimed that it had added 100,000 new members in the weeks following he Sandy Hook massacre. "Our goal is to get to 5 million before this debate is over," a representative of the group told Politico. If all of the NRA's numbers are to be believed, it will hit its target by this fall {2013}.

UPDATE: A source writes in with another strong indication that the NRA's true size is closer to 3 million. The NRA gives members a free subscription to one of four magazines: American Rifleman, American Hunter, America's 1st Freedom, or NRA InSights. The first three magazines are audited by the Alliance for Audited Media, which as of July gave them a combined paid circulation (including newsstand sales) of 3.1 million. NRA InSights is an online-only magazine for kids, with a circulation of 25,000. Though some NRA members may opt out of a free magazine, it's likely that others pay to subscribe to more than one of them. Add in the fact that non-NRA members can pick up the magazines on the newsstand, and the 3.1 million figure is almost certainly an upper-bound for the NRA's true size.
