Greetings,

I have what appears to be a K-frame rear sight assembly.

The odd part is the distance from the elevation screw hole to the mounting hole is about 1.760". Much shorter than the sights on my M-67 and M-14.

It certainly does not match up with any of my N-frame pistols.

Is there a chart showing the various hole patterns and models used on?

Cheers,

Dave
