maybe long guns that have more inherent pointability/accuracy and aren't as prone to "gangsta hold"
I wouldn't count on that:
I remember drafting a bit of a study comparing gangs with primitive tribes and the types of warfare they conducted. There were a lot of parallels. One of them is taking deliberate actions to make warfare less lethal by using a mixture of superstition, tradition, and other methods. It's a bit like monkey/ape warfare as well - more screeching than fighting, and while there's a steady stream of bodies, it's generally not so huge as to threaten the tribe's existence.
Examples would include holding guns and firing them inaccurately - because if you become accurate that means your enemies have to become accurate and that results in too much death all around.
Ancient tribes had various rituals, on island, for example, any warrior that killed his opponent had to immediately leave the battlefield to ritually cleanse himself. Doesn't make sense for that battle, but if you think about it, this is when combat is even more physical, so the warrior is probably tired after his fight, thus more likely to lose the next, he's proven that he's valuable, and it's better to ensure that he's available for a later fight than to 'win' this one.
