Funny to see this post in the thread.
Turns out the HDs did not work out for me, fwiw.
I continually had issues with the height and sharpness of the rear sights. In addition, having picked yellow for reasons which now escape me, I really did have problems seeing that color.
(In retrospect perhaps I should have gone orange. Maybe by age 58, my photo-receptors for green/yellow are not that great anymore? I wonder if anyone has any data on best color for aging Baby Boomer eye sight? Maybe we need a pole.
)
I went ahead and put the glow in the dark HK sights back on. I'm mulling over just painting my rears black, but am on the hunt for a ideas on a good front sight. High on the shopping list are Orange color, highly visible, and a manageable price for two. Also need zero change in POI, so stock height. I'd love it if there was a balance for CCW and USPSA, since I'd want the same sight for my EDC P30SK as well as competition VP9. I don't think I'd really want a big fat dot anymore, either.
I had a 10 8 FO on my M&P (since sold) but maybe I am in the minority but I was never that impressed with the light capture of the fiber rod. And I tried several of the colors too.
All that being said, are these Dawson Precision Tritium Sights close to what I am looking for? I'll definitely go check them out.
