The green fibre optic rod on the rear sight of my HW40 snapped recently and I’m having difficulty finding a replacement.

Does anyone know where I can get hold of one? I’ve checked Chambers but they don’t seem to stock them.

I’m also wondering whether, even if I do manage to get hold of a straight rod of the correct gauge, I’d be able to bend it into the U shape needed to fit the rear sight blade without it snapping.

The closest thing I’ve been able to find (and I’m not even sure if it’s the correct gauge) is this.

If anyone has any experience of this or can offer any advice I’ll be very grateful.

Thanks
