Making a 2D gun spin from recoil when it shoots

Hi guys, I am trying to clone the game "Flip the Gun" as an exercise. [

Here is the behaviour I have so far
[https://drive.google.com/file/d/1-v3m69F_MVWQQrvUbENMo0djRnyBVN-D/view?usp=sharing].


And here is the code I am using:

Code (CSharp):

1.     if (Input.GetKeyDown(KeyCode.Space))
2.     {
3.         rigidbody2D.AddForceAtPosition(
4.                     transform.position-recoilPoint.transform.position * recoilForce,
5.                     recoilPoint.position,
6.                     ForceMode2D.Impulse
7.         );
8.     }

As you can see in the video, the gun is moving too fast and rotating too fast. It seems out of control. How should i change the code to make the gun spin slower and act just like in the first video? Thank you.
