Best co2 pistol with insane kick

[Oneshotonekill]

Hi guys 

birthday is coming up and I’m after a new pistol but I’m fed up with using green gas so I want co2. Now the pistols that I’ve got havnt got that much kick and I want one that is tactical and got insane kick. I was looking at the sps falcon from redwolf Airsoft 

many thanks again
