The TruGlo Fiber-Optic Pro Sight Set (brand part number TG132G2) replaces the factory sights on a Glock 20 or 21 with a high-visibility front-and-rear pairing built for faster target acquisition. TruGlo pairs a bright red fiber-optic front sight with a patented light reflector that pulls in ambient light from every angle and channels it into the fiber, keeping the dot glowing even as shooting light fades. The blacked-out, serrated rear sight cuts glare and boosts contrast against the front dot, so the eye locks onto the sight picture faster under stress. Because the set installs as a direct swap and fits standard holsters, it’s an easy upgrade for a duty or personal-defense Glock in 10mm or .45 ACP without any holster modification.
