I saw 2 Guns last night and if you want to see a funny action movie this weekend. You should definitely check it out. Also ignore the trailer, it doesn't do the movie justice.
It has all the one liners and riffing off of each other that buddy cop comedies have but with none of the lame Ebony and Ivory type jokes. Even if you don't like that aspect of the movie, you should see it anyways for all the action sequences and the intrigue about what's going on in the movie. Both of them are undercover agents and think that the other is a real deal trafficker and that's all I'm going to say about it. Don't want to spoil too much.
