If I understand the thread... Mine has a single screw rear sight, and the front is a gold dot.
The grips are labeled 303, which seems to jive with the sales sheet you posted. I have found them to be one of the most comfortable grips I have ever used.
Mine were REALLY nasty with years of gunk and crud. Fortunately, my other hobby is motorsickles, so I threw them in my commercial ultrasonic cleaner. After about 20 minutes they came out brand spanky new clean. Too bad I can't fix the chip...
It is really just a WELL made gun. The quality of machining and fit of everything is just superb. I can see why they have such a loyal following. (Age has brought me a much greater understanding with regard to how things are made.)
I'm glad I kept it all these years. Always feels good to know when you got a smokin' deal.
If anyone has an unbroken set of these grips that they would like to sell... I'd certainly be interested.
Thanks again for your help.
Enjoying the learning.
Best,
