Hello, today I have been trying to hook into CrackShot and give someone a gun.

At the top of my class I put:
  CSUtility csu;

and I made a method:

        public void giveGuns(Player p, int amnt) {
        if (p != null)
                csu.giveWeapon(p, "MP7", 1);
    }

However it is throwing a NullPointerException. The gun MP7 is there, so that can't be the issue. Am I doing anything wrong here?

You've declared the variable 'csu', but you have not assigned any value to it.
