First, I am all for raising a non-violent child. My husband and I are both veterans for peace, and we want our son to avoid acting out in dangerous ways.
Second, let me tell you that when my son was younger, there was NO WAY IN HELL I was going to let play with toy guns.
Now, let me tell you that I have eaten a little crow on this, grown a bit as a parent, done a lot of reading on the subject (from people whose child development philosophies I admire-- because I like to read up) and these are the conclusions I've come to, for now.
My son is five. His 'weapons' interest started with bows and arrow, which we fashioned out of stick and string. He wanted to 'go elk hunting', so he pretended that. He was not allowed to aim at any living thing, only targets.
He became interested in guns and talked about them incessantly. At an arcade, we let him trade his tickets in for a foam disc gun. Same rules about aiming. (If he aims at us, it goes away for a week. I'm hardcore about this.) What we noticed is that the novelty wears off pretty quickly.
My husband and I have agreed that we do not buy weapon toys as presents. He is allowed to make them-- he's made some awesome tinkertoy 'shooters' with a spring, launching tinkertoy pieces off of it. He receives a small allowance to practice spending money and knows he has to save up if he want a lightsaber. (No, he's never seen Star Wars and we haven't exposed him to violent media.) We currently have a 'lightsaber' made from a flashlight and a sheet of colored plastic rolled up into a tube.
However, the nonviolence that we teach isn't just in what we do or don't allow. It's also in how we parent our son and how we teach conflict resolution. I live in Portland; on Tuesday there was a shooting at the mall I used to work at--it's scary. That said, none of these violent crimes and tragedies have happened in a vacuum. There are usually more profound indicators that a person is having severe problems, once we start to really investigate.
I'm also going to say that, in regard to toy guns/weapons, I think if we had forbidden them, they would have become even more alluring. We have guns stored very safely (double-locked, ammunition stored locked and in a separate place) in our home. We do plan on taking our son to a gun club and using their shooting range when he is a bit older, just so he can truly understand what a gun can do. For now, it's all pretend play. He's not asking to watch violent shows, and even wants me to turn off old vintage cartoons when anything even mildly violent (like a boxing match) or hurtful happens.
So, I've got to say, I think this is one of those times when, as parents, we must really balance out a lot of our fears with appropriate amounts of freedoms. What is the price of your boys not having nerf guns to play with their buddies? You don't say your boys ages, but ask yourself this: do you think they could follow simple safety rules regarding this sort of play? Could you find a way for them to 'earn' the guns themselves, so that they really do have to prioritize that toy above other things?
And I haven't read the other comments, but I will say that someone can easily point out the damage sticks have done to eyes, etc. There are always things we hope for our children, and things we fear. We have to figure out how to balance our hopes and fears, the risks we let our children take when we know they can likely handle the risk. I think that there are ways to ensure that this sort of fantasy play stays *safe* in reality and is another way we can get a glimpse into our children's thoughts, imaginations and even their deeper lives if we choose to.
One link that I really like- a conversation about negotiating violent play, taken from a classroom, and the teacher's (author Jane Katch) thoughts about that conversation. I found it very enlightening:

There are myriad other articles, including interviews on the subject with Bruno Bettelheim, who lived through WW2 in Austria, spending 11 months as a child in Dachau and Buchenwald concentration camps, which is one reason I take his opinions with a degree of gravity. You can google "Bettelheim Violent Play" and find a lot of good, thought-provoking information.
I know it was a long answer--just wanted to share how I am evolving as a parent on this subject. I have never bought the 'I played with guns and I'm fine' line, personally, for myself-- I needed to examine why I am choosing what I do as a parent here and now.
