Keeping an Object Locked In Position Around Another

Hi Guys,

I'm making a script in which objects defined as weapons can be dragged to the player and placed in position using physics. This is achieved using two empty objects, Player_Attach_Point and Weapon_Attach_Point, as reference points to move the weapon to a desired location after it hits a SphereCast. However, I wanted to set the player's weapon to remain in a constant position upon rotation and movement. I tried using a FixedJoint between the player and the weapon, but this caused the camera and player to go nuts (rotating really, really fast etc.)

Can anyone suggest a reasonable way of making the weapon stay in place indefinitely?

Cheers,
