Does anybody know if a Weihrauch front sight will fit the barrel dovetail of the Webley Omega? They appear to be close to the same size, but the Weihrauch dovetail is pressed into the steel, where the Omega dovetail is finely machined into the barrel.

I don't know if the angles are the same, and as my colleague at work is wont to say, assumption is the mother of all f**kups.
