Green front and orange rear is one of the most field-tested and trusted sight picture color combinations for defensive pistol use - strong, immediately readable contrast between front and rear that pulls the eye to the front sight naturally without any conscious deliberation. The Trijicon Bright and Tough Glock Suppressor Sights 600662 delivers that proven color configuration in a suppressor-height profile purpose-built for standard and compact Glock pistols. The 600662 fits Glock models 17, 17L, 19, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 34, 35, 37, 38, 39, and 45 - covering the most widely owned and carried standard-frame Glock configurations for civilian defensive carry and law enforcement duty use. The Suppressor Height Sights 600662 purpose-built fit ensures correct dovetail installation and proper three-dot alignment on the compatible platforms. The Tactical Tritium Sights 600662 green front and orange rear combination creates an immediately distinguishable color difference between front and rear sights - the green front draws the eye forward naturally while the warm orange rear provides visible contrast that completes the three-dot picture quickly. White rings around all three Trijicon Bright and Tough tritium lamps maintain excellent daylight visibility across all lighting conditions. The Trijicon Glock Suppressor Sights 600662 elevated profile clears a suppressor body for proper three-dot alignment that standard-height sights cannot provide with a can attached. The Iron Sights suppressor-height configuration works equally well on an unsuppressed Glock without penalty. The 600662 self-luminous tritium-phosphor lamps provide continuous three-dot illumination in complete darkness. Sapphire jewel lamp caps, silicone rubber cushioning, and aluminum cylinder protection handle heavy recoil. Please note that orange lamps are warranted for 5 years from the date of manufacture.
