For what it's worth, we are still carrying our P2000 .40's, and have only been told we'll have the new Glocks by 2021.
I just ordered a new front sight and Talon Grip decals for my service pistol. My aging eyes were not doing their best with the old, faded 13 year-old Meprolight Tru Dots. I tried the Trijicon HD sights with the orange front sight and it was even more blurry for my eyes. Nice sights, especially for those with better vision, but they blur out with my eyes far more than a white dot. I have Big Dots on most of my carry pistols, but they are not authorized at work.
Interestingly, Meprolight and Truglo both responded promptly and professionally to questions about sight dimensions. Meprolight was particularly helpful. HK did not respond at all to my inquiry about OEM tritium front sight heights, sent from my Gov't email. Go figure.
