I would say that for someone who probably is a gun aficionado, it would probably be illusion-breaking to see this. But for someone like me who hasn't even shot a gun at all in my life, I'm ok with it. Hell, some guns even look badass, like Thorn. And I know Thorn looks unbelievably big in a character's hand. I think Bungie had to make the decision of doing things a bit more realistically vs. just having some fun and realizing Destiny is not as serious as they shaped t up to be originally. Which I think it was a great decision.
