i play HC most of the time so up close power is not as relavent. 5-7 all day every day on 20rnds. its a beast for me.
Five-seveN extended clip for me all the way, it gives it a ridiculously big clip so you practically don't have to reload 'till you die if you're accurate. Fast mag is also very useful becaue it will sitll have a clip of 20 and takes like a second to reload, so yeah great weapon
