It has the fine-tune rear sight. Does it also have the fine-tune front sight?.

Check the 'notches' for the elevator on the side of the rear sight. Are any chipped or broken? Check the elevator for function - Does it move without pushing the button in? (Sometimes, the elevator 'finger' will break off but the 'notches' on the 'ladder' will be intact. It will move without pushing the button in then too).

Does the rear sight number match the frame number? It may not - but somewhat of a plus if it does...
