Making a pawn go where you want it

I want to have a pawn that goes to a spot where my crosshair is. Basically, I look at a point in the ground and the pawns will go to the spot. It's pretty hard though, any ideas how to do this?

You could measure the distance between the camera and the spot where the crosshair is pointing with GetCollideDistance() and with a bit of trigonometry you should be able to calculate the X, Y and Z coordinates of that point.
Another option that crossed my mind is to launch a pawn from the camera's position to the crosshair's direction and mark the spot where it collides with the ground.

I was considering trig by getting the pitch of the camera then using tan, but I wanted to try the projectile idea first. how would you find the point where the pawn hits the ground?

self.camera_pitch is in radians right?

Yep, all the pitches and yaws are in radians.
how would you find the point where the pawn hits the ground?
Use a pawn with a small bounding box and fly to the camera's direction with flymove(). When flymove() returns false the pawn has collided with something and that's your point (the pawn's X, Y and Z coordinates).
