Washington Post fact checkers give two Pinocchio's to President Obama's claim that states with the most gun laws tend to have the fewest gun deaths, which means the statement included "significant omissions and/or exaggerations," although the author notes he waivered between two and three Pinocchio's, with three being in the "mostly false" category.

In the article the WaPo explains that when you exclude suicides, which account for 60% of gun deaths, then there is a significant change in where a state might rank in the number of gun deaths per 100,000 people.
First, the WaPo notes that the data is "mixed" on whether stricter gun laws lead to fewer suicides:
Some might argue that it is wrong to exclude suicides from the data, as less access to guns might result in fewer suicides. The data on that is mixed. Gun-related suicides might decline, but studies have shown little connection between suicides and access to guns. A 2004 report published by the National Academy of Sciences concluded that “some gun control policies may reduce the number of gun suicides, but they have not yet been shown to reduce the overall risk of suicide in any population.”
Japan, for instance, has among the world’s most-restrictive gun-control regimes — and yet also has among the world’s highest suicide rates, almost double the U.S. suicide rate.
Second, once you exclude suicides:
Alaska, ranked 50th on the National Journal list, moved up to 25th place. Utah, 31st on the list, jumped to 8th place. Hawaii remains in 1st place, but the top six now include Vermont, New Hampshire, South Dakota, Iowa and Maine. Indeed, half of the 10 states with the lowest gun-death rates turn out to be states with less-restrictive gun laws.
Meanwhile, Maryland — a more urban state — fell from 15th place to 45th, even though it has very tough gun laws. Illinois dropped from 11th place to 38th, and New York fell from 3rd to 15th.
The WaPo concluded that:
While gun suicides are certainly a serious issue — and account for more than 60 percent of gun deaths — the evidence is mixed on whether restricting gun purchases would affect the overall suicide rate. In any case, the president’s policy proposals are aimed at mass shootings, not suicides.
In short, I, along with almost all of the people on DU, support toughening our gun laws to include UBCs and additional training. But stricter gun laws isn't the panacea it is made out to be, and in some states -- notably Maryland -- such laws have had little impact on gun violence.
