M686 Pinned front sight???
How can you tell if your Model 686 has an interchangeable pinned front sight?
I notice below the front sight (red ramp) what appears to be a pin running perpendicular to the front sight above. Is that the pin?
Thinking about the SDB Gold Bead or possibly a light gathering SDM Super Sight; anyone use these for poor eyesight? Any opinions would be greatly appreciated.
