Reloading twice unfreezes all physical entities (props, ragdolls, etc.) you've spawned so far. If it is a ragdoll, all its bones will be unfrozen. Reloading with the Physgun (R by default) unfreezes the object and all of it's 'associated' props being looked at by the player. The Physgun can also straighten out the angles of a prop, done by holding the Sprint key (Left Shift by default) & the tertiary trigger and moving the mouse around.

The fourth trigger (mouse wheel) allows the user to pull the grabbed target to them or push it away, although the same thing can be done by holding USE and pressing the Forward and/or Backpedal key. The tertiary trigger (USE key, E by default) when held allows the user to rotate the held object using the mouse. Non-physical entities like the majority of NPCs, Vehicles, and players cannot be frozen. The secondary trigger (Secondary fire, right mouse button by default) allows the user to freeze the held object in place regardless of where it is. Anything that touches the beam or vice versa will be grabbed by the user and can then be manipulated into different positions. The primary trigger (Primary fire, left mouse button by default) when held emits a long blue or a player-determined color beam from the front of the gun.
