TAPCO TAP22039 Tritium Night Sight Set for MOS Glock Pistols

The TAPCO TAP22039 tritium night sight set transforms MOS-equipped Glock pistols into reliable low-light performers. This precision sight system delivers consistent target acquisition in complete darkness through self-illuminating tritium inserts that maintain brightness for over 12 years without batteries or external power sources.

What Makes This Different

Unlike standard polymer sights, the TAP22039 features genuine Swiss tritium vials that provide instant sight picture recognition in zero-light conditions. The reinforced steel construction withstands repeated slide cycling and holster draw cycles that would damage factory plastic sights. Each sight undergoes individual calibration to ensure proper point-of-impact alignment straight from the package.

Key Features

• Genuine tritium gas tubes provide 12+ year illumination lifespan
• Machined steel construction resists impact and wear damage
• MOS-specific fitment for Glock models with optics mounting system
• White outline rings enhance daylight visibility and target contrast
• Factory-zeroed alignment reduces installation adjustment time
• Snag-resistant profile prevents clothing and holster hang-ups
• Corrosion-resistant finish maintains appearance through extended use

Field performance testing demonstrates consistent 2-inch groups at 25 yards under various lighting conditions. Law enforcement agencies report improved qualification scores during night fire exercises when officers transition from standard sights to tritium-equipped pistols. The self-contained tritium system eliminates battery failures that plague electronic sight systems during critical situations.
