More guns will probably not decrease the crime rate as far as street crime is concerned. Unless a "law biding" citizen is walking around with a gun in his hand, he is still subject to a mugging. However, more guns will probably increase gun deaths for the simple fact there will be more guns in households. A greater chance of accidents, or domestic rage.
Places with higher gun ownership rates also have higher firearms-related deaths, a study finds. In the study, published in the American Journal of Medicine, researchers analyzed gun ownership rates, crime rates and deaths from firearms across 27 developed countries around the world.

Under current conditions, increasing guns will increase deaths - by whatever degree.
In order to preserve existing individual liberties, we must institution protective principles in-measure to the laws, regulations, or other systems we instrument.
In other words, we must change current conditions to maintain the individual liberties we have today. Changed conditions can allow the same, or increased, gun ownership without more deaths — or even less deaths.
This "protective principle" I have written about here, and call a "Commutative Principle". I propose this principle as a fair way to regulate rights / liberties, as a guarantor that means are contemplated for the safe absence of regulation.
No laws were necessary with the first few cars on the road... But as the numbers increased, laws became necessary. Same with guns... Study the Founding Fathers intentions.
Fact every state that has passed a right to carry by its citizens has in fact see a 10% or greater violent crime rate reduction. More guns has actually equaled fewer deaths and more citizens being able to protect themselves something you can not do for them. Just look at the numbers.
In my view, there is some good evidence that more guns increases gun-related violence. There's also a possibility that guns deter some violence. Everyone on all sides likes to pretend that they can measure both of these effects against each other, but that is almost always suspect.
The most careful analyses routinely find that, when you control for all of the variables that matter, gun control might help reduce gun violence but it would not be a panacea. The U.S.' high levels of gun violence and death are not actually only or even primarily due to our relatively lax gun laws or poor gun law enforcement. There are a ton of sociological factors, from ethnic heterogeneity and residential segregation to geographic patterns to a militaristic culture to income inequality. Those should be resolved primarily.
