Questions & Answers
if need be could you still one hand rack a slide with this sight Expert Answer

The Truglo TFX FNX45 Tritium/Fiber Optic Green 3 Dot Night Sight may not sit high enough to comfortable operate the slide using the sight but could be done.

How long does the tritium/fiber optic green element last? Expert Answer

The fiber optic portion of the sight should last indefinitely. The tritium element typically has a half life of 10-12 years, meaning it will still glow however will be half as bright.
