This front sight pairs with the Heinie Glock 43 rear and features the single tritium dot for low-light and nightime use. Using the Heinie front and rear Glock sight combination will not alter your POA/POI. This front sight is .215 tall and .125 in width. This is the same front sight as part number 318F/322F.
HSP Inc. does not accept any returns or exchanges on any product that has been installed and/or is in used condition. 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, the tritium only will be replaced. Turn around time to replace a broken or defective tritium vial usually takes about 3-4 weeks.
