I have a Springfield XDE 3.3 in 9mm and I love everything about the gun except the sights. I'm not a fan of the fiber optic front sight and even the white dots on the rear are too small for my old eyes. I'm told that the Springfield sights are interchangeable with Sig sights. Does anyone know (or have a guess) at what combination of Sig white dot contrast sights I would use on the XDE (#6, #8, etc. ?)
(ps: I'm not a night sight fan so that is not an option for me)

A #8 front and #10 rear should fit.
I used a SA rear on my 229 that needed a #10 from Ameriglo.

Night Fision has sights for that model with different colored fronts and different rear blade styles.

I like XS DXT2 big dot with an orange front on my 365, easy to see with or without my glasses on.
They have a smaller dot also.
