There are several documented cases where armed citizens have stopped mass attacks by gunmen. Let me list a few: The Pearl, Mississippi school shooting was stopped by the vice principal Joel Myrick with a Colt .45, The Appalachian School shooting was stopped by two students with handguns. Both of the above incidents were stopped by the armed citizens threatening the shooter without firing.

Just recently, in Early Texas, armed citizen Vic Stacy shot and stopped a deranged man who had just murdered two neighbors and was firing at police with a rifle. Stacy made a very long shot with his revolver, three times as far as the perpetrator was from the police officer, who had an AR-15 type rifle.

That sounds like a very good story... but it never made the national news.
I wonder who made the decision to spike that story.
Of course, when a mass shooting is stopped by an armed citizen, there are not as many victims. This leads to the charge that it would not really have been a “mass shooting”.
I have added this incident at the request of a reader:
Abraham Dickman had a history of anger against employees of the AT&T store in New York Mills, New York. On May 27th, 2010, he walked into the store with a .357 and a list of six employees. He shot the first employee, but was stopped from further attacks when Donald J. Moore, an off duty police officer who was allowed to carry his own handgun when not on duty, drew and fired his .40 caliber, killing Mr. Dickman before he could fire any more shots.

Here is another likely candidate.
College Park, GA, May 4, 2009.
Two gunman entered a party and ordered the men separated from the women. Then they started counting bullets. “The other guy asked how many (bullets) he had. He said he had enough,” said Bailey.
When one of the assailants prepared to rape a girl, a student was able to access a handgun and engage the two attackers in a firefight, driving one off and killing the other before the thug could rape his girlfriend.
“I think all of us are really cognizant of the fact that we could have all been killed,” said Bailey.

Clackamas Mall Shooting
I include this story because it is recent and has been getting some interest on the net. This case is not as clear as the others listed. This incident is similar to the more common defensive uses of guns because the mere display of the gun was enough to defuse the situation. We can never know if the shooter decided to commit suicide because he was confronted by Nick Meli, the CCW holder, as the shooter is dead. However, many mass shooters commit suicide when they know that armed resistance is at hand.

I have added this link as suggested by Doug Kuiphoff in the comments. I do not think that it qualifies as a mass shooting stopped, because the potential shooter says that he did not intend to shoot anyone, but to kidnap some people. Still, it is an interesting story, so here is the link:

Added, from 2012. Consider that the Plymouth shooting incident happened just three months before Sandy Hook. Mark Ktytor, a concealed carry permit holder, stopped a likely mass killing before it reached enough victims to officially quallify. From the citizensvoice.com:
"Mark Ktytor?" the latest in the stream of reporters asked, trying to put a face to the name of the man investigators credited with preventing a fatal bar shooting last weekend from escalating into a massacre.Link to Plymouth, PA Shooting story
This is the oldest incident that I have found. I include it because it is in the "modern era". It occurred in 1915, in Brunswick, Georgia. It is a bit unusual in that 20 or more people were wounded and at least five killed. The citizen who finally stopped the slaughter obtained the pistol used from a hardware store during the attack. The shotgun was actually a double barreled model.
Angered by losses in a real estate deal, Monroe Phillips, a lead business man, ran amuck today with an automatic shotgun and killed five men and wounded twenty others before he himself was killed. Phillips was shot dead by E.C. Butts, a lawyer, while he was trying to fire upon citizens who appeared in the street.
