Night Sights for a New P30 V2

I would like to add night sights to my new P30, V2 LEM. The night sights I am most attracted to are the Heinie Straight Eights as I much prefer "dotted I" sights to "Three Dot" sights and also prefer some color change, front sight to rear sight if I can get it. The Heinies would seem best for the P30 at least for me. However when I read posts from members who have installed them or had them installed most comment that it took a considerable amount of work to fit them to the P30 slide. I even saw at least one post, all be it, from a couple years ago commenting about having to shave off material from the bottom of the rear sight in order to get a proper fit and another talking about shaving the screw heads. That seemed a good bit of fitting for sights that are listed by HKParts Net for the P30. So I was wondering if these night sights do in fact still require a good deal of fit work to install or if they are closer to how some of the other sights identified as for the P30 are fitting?

If I was not comfortable with the amount of work required to fit the Heinies, I would likely go with the "XS Big Dots". There are things I like and don't like about the Big Dots but they are "Dotted I" sights and I would still prefer those to 3 dot designs. Maybe in a dead heat with the XS sights would be some combination of fiberoptic sights like the TruGlo's if they make them for the P30 or even a HiViz FO front sight and some appropriate rear sight in combination. Does anyone have a recommendation for a good rear sight match to a HiViz Fiberoptic front sight?
