In my quest for diamond SMGs I waited to do the Chicom until last. I thought I would despise the Chicom, but I have been pleasantly surprised. I believe it is because I burst fire sub consciously to control recoil. Do you like or not like the Chicom?
It's a great gun. Just slap Quickdraw and Fast Mags on it plus Dexterity and you're good to RnG with it. It's my third best SMG after the PDW and MSMC. It's my second to the last SMG I did on my diamond camo quest.
