H & R Officers rear sight

Posted by Don Huskins on Tuesday, 27 January 2015, at 6:25 p.m.

Thinking about adding a rear 1879 sight to my H & R Officers, I have been told that I might run in to an issue with the sight screws, original being Whitworth screw pattern and requiring a Whitworth tap set. The remedy seem to be to use a American screw pattern. Has any one attempted this or know anything about this issue?
