This next gun is a M66-5, the last of the configurations before they added the lock to this model. S/N CEC2xxx, this gun shipped to RSR on 4/25/2000. This is the engineering change that moved the firing pin from the hammer to the frame, as well as adding the integral frame lug. Again, the rubber grips were replaced by something that I can stomach..
The front sight has also been replaced with a Patridge style... Love it!
