Glock Classic Tritium Rear Night Sight

Glock Classic Tritium Rear Night Sight

The Heinie Classic design is the original rear design produced by Heinie.  It is CNC machined from Bar Stock for durability.  It features a serrated rear face and the legendary single tritium insert (for low light and night time shooting) that aligns vertically with front sight tritium insert (when used as a set).  This vertical alignment is proven to be faster and less confusing for the human eye than the traditional horizontal alignment. 

No fitting or modifications required for installation.

Fits all Glock generations except models G42/43(X) and G48.  Not for use with suppressors or MOS/RMR plates.

*Rust Resistant Finish*

If you suspect your product is defective (as in, the tritium does not glow), the product will have to be returned to Heinie for inspection. Heinie cannot send out replacement products without having the originally purchased product in hand. If the item is determined defective, Heinie will send the sight out for the tritium vial to be replaced (in the originally purchased product). We do not replace the entire sight, only the tritium will be replaced. Turn around time to replace a broken or defective tritium vial usually takes about 3-4 weeks.
