So I finally found the single six that I had been looking for.
4 5/8 barrel, both cylinders, and just so happens to be a bicentennial.
Took it to the range this evening, and it worked great.
Until, on the 27th round, the front sight fell off.
It is apparent that at some time in the past, the screw either broke, or stripped, and somebody did a poor job of soldering it back on.
Should I clean, cold blue, and epoxy, or just take it to a gunsmith, or what?
I am open to ideas, and why or why not they would work.
