Cons
- •The front sight sometimes glows dimmer than the rear sights, which can affect overall nighttime aiming effectiveness.
- •Some users report the factory sight required a bit of fitting or minor modification with tools like a Dremel to achieve perfect installation.
- •Slight alignment issues out of the box, with no clear instructions or hardware included for adjustment—fix requires DIY shims and threaocking compounds.
- •Edges of the sight, especially on smaller guns like the Shield or similar models, can catch on the hand during slide cycling; corners could benefit from smoothing or narrowing.
- •Customer support and warranty processes are cumbersome, requiring full sight set removal and return for just one defective piece, increasing cost and hassle due to gunsmith involvement.

Bottom Line
The MEPROLIGHT MEPRO TRU-DOT Green Tritium Glow Night Sight is a solid, durable upgrade that dramatically improves low-light target visibility on Mossberg 500 shotguns without complicated installation. While its bright glow and sleek fit are definite pluses, be prepared for potential minor fitting or alignment tweaks and a somewhat frustrating customer service experience if issues arise. This sight is ideal for users who want reliable, consistent tritium illumination and are comfortable with basic installation adjustments. If you value easier warranty handling or need sights with perfectly smooth edges for faster handling, you might want to explore other night sights, but for anyone sticking with the Mossberg 500, this remains a top-tier tritium front sight option.
