Lollipop sights - Ameriglo Pro I-Dot Tritium Night Sight Set - S&W M&P, ProGlo Green Front w/ Orange Outline & Single Dot Green Rear

My first night sights were TruGlo TFX and the are great. But I wanted something a little quicker so I bought these. The front sight picks up very fast day (orange) or night (tritium). The rear sight is a little hard to pick up both day and night. In the day, the index line is too thin to pick up quickly and at night, the rear tritium is a bit on the small side and not quite bright enough for me. Maybe they will grip on me, but at this point I still prefer the TFXs, but they're on my wife's gun now.
