Fiber Optic Sights: Fiber optic sights use colored rods made of a light-gathering material to provide enhanced visibility and aiming precision. The "red fiber optic" indicates that the front sight likely has a red-colored fiber optic rod. Fiber optic sights are particularly effective in bright lighting conditions.
Black Housing: The sights are housed in a black housing. This refers to the framework or casing that holds the fiber optic rods in place.
HD Sights: The term "HD" likely stands for high-definition, suggesting that these sights are designed for improved clarity and precise aiming.
Compatibility with Glock: The sight set is designed to fit Glock pistols. It's essential to verify compatibility with your specific Glock model before making a purchase.
