I don't think there is anything to give you a preferential advantage over, say younger players. But there are guns with higher 'assist' capabilities. For example, some guns have a might higher aim assist stat; people like to say that MIDA multi-tool is great for new players because of the ease of aiming and high aim assist to help you hit targets. If you look at this chart http://db.planetdestiny.com/items/weapons/primary/scout you can see that MIDA has a 90 aim assist rating. You can also roll legendary guns with aim assist perks like hidden hand. If you get a gun with high natural aim assist plus hidden hand, plus a scope with enhanced target acquisition, this can help somewhat. They used to say that if you used bladedancer with high agility, ran Radiant Dance Machines exotic boots and MIDA multitool (which grants you increased agility), you moved like greased lightning. So there are perks for agility or aim assist, but of course anyone can use them (the young people could use them as well). But most people might favor other perks over enhanced aim assist, so you might get a little edge in that area at the cost of things like range or reload perks or damage perks.
