Ssiscool Continuity mistake: The T-1000 has the gun holster on his left side and takes the gun out with his left hand when the guard in the psych ward hits the alarm. A few scenes later when the T-800 (Arnie) asks Sarah to 'come with me if you want to live' the T-1000 walks through the cell doors, the holster is on the right hand side and the gun in his right hand. (01:10:00 - 01:12:00)
Suggested correction: The T-1000 can change shape at will so it is safe to say the he changed hands with the gun and switched its holster to suit. The T-1000 uses both hands throughout the film to hold and shoot his gun.
Continuity mistake: At Cyberdine, Gibbons' chair position differs between the shot when the second guard arrives and after he finds him laying on the floor.
Sacha Continuity mistake: While in the police car, escaping from the T-1000, when Sarah says "John, it was stupid of you to go there", her ponytail is either brushed and neat, or messy and all over her shoulder, depending on whether the shot is from behind or the front respectively.

The position is inconsistent many times.

Continuity mistake: When the Terminator smashes the driver's window of the blue station wagon, there is a large section of glass at the top of the door that is stuck in the runner of the door. In the next shot as the Terminator is closing the door, this same section of glass is now missing. Not enough time has passed in the shots for it to disappear and there's no sound of it dropping. (01:13:25)

In the next shot, when we can see Sarah through the hole as it 'heals', we can see that the head is already in its regular shape as the hole fills.
