Efficiency is one of many traits we have. It seems lacking however.

It's virtually just an extended mag. To make it more standing out, I'd recommend to also give it -17% in reload, draw and holster time, as this is how efficiency can also be shown.
"But Methelin, isn't -17% reload time too much?"
No, Quick Hand I mod, that is the first tier, grants -30% reload time. In my opinion, this wouldn't make the trait overpowered, while still making it more versatile.
