The Extraordinary Rendition Submachine Gun will be great to have in PvE or PvP. Mulitkill Clip: Reloading grants increased damage based on the number of rapid kills made beforehand.
Tap the Trigger plus the previously selected Zen Moment should be a good combination. I’d much rather have the guaranteed stability and accuracy on the initial trigger pull than count on myself to activate Multikill Clip in PvP. Tap the Trigger is a no-brainer for me here. As you put damage on your target, you will find the weapon gains stability, allowing you to keep the bullets flying in the direction you want to help you score that kill.
