MN,
Not sure what you mean by 9 pins? If your gun was made in the Early 70's it should have 5 pins on the right lock and 4 pins on the left lock. Go to the Griffin & Howe Used Gun website http://www.griffinhowe.com/usedgun-sg.cfm. There is a Beretta S2 listed. The photos of the gun will show you the pin configuration. Then look at the price and you did very well to get into an S2 for $2200.

To anyone else,
Just curious, has anyone actually seen a 60's period SO gun marked as an SO? The only ones I've seen were marked as an S2, S3, S3EL, S3EELL.

Thanks
