Yes. Is that the Cylinder & Slide you mentioned before?
I can see there is less meat on that dovetail than the one on Hizzie's gun. Given the option, I'd prefer the version Don Williams does. But I'm not quite as convinced as Marc @ Gemini is that there isn't enough meat to keep the dovetailed front sight in place. I think starting with an oversized blank and fitting it tight
should keep it in as well as can be kept.
FWIW, Marc told me he can do whatever we want, he just advises against a dovetail. And he is not a fan of epoxy-on XS sights and actually refuses to do those. I don't blame him there, I'm not particularly enthusiastic about a glued-on front sight myself, though I think it would be fine with wadcutters, a gun that saw a steady diet of +P loads, would almost certainly find the front sight laying on the ground one day.
If I were the 'Smith in question I would probably re-engineer the XS to work better. By drilling a pin hole through the sight blade and through the post of steel that you leave in place which you epoxy the sight to. Epoxy + Pinning would probably keep the sight firmly in place...basically forever.
Maybe I should go take the machining class on campus, buy a table-top lathe, a good drill press, and a stack of XS sights and just make it like it should be...
