I bought the last extremity from the crucible vendor for iron banner and fell in love. It does 73 a headshot The accuracy is amazing and it is a sneaky strong gun. You take out snipers before they get their second shot of if they miss the first because they took one to the face. Vendor version is a great option for 6v6 game modes. For trials I would probably want firefly. Smallbore and I'm not sure on the first perk. Lots of good options. I highly recommend picking it up when you have 150 marks to spend
