The Meprolight ML11517 Tru-Dot night sights for HK USP Compact deliver reliable low-light target acquisition without batteries, electronics, or switches. Each sight blade contains its own tritium light source, producing a bright green/green three-dot sight picture that remains visible in near-total darkness and works equally well in daylight. If you carry a compact HK for duty, defense, or sport shooting and need sights that perform when ambient light fails, these are built to function in conditions where conventional sights become a liability.

Tritium-based night sights work through radioactive decay—a passive light source that requires no charging, no maintenance, and no operator input. Unlike electronic solutions, there's nothing to fail or forget. The front blade stays green for contrast against the rear sights, creating a natural sight picture that tracks instinctively. Meprolight's design has been proven in military and law enforcement service across NATO, U.S., and Israeli forces, a pedigree that speaks to durability and real-world reliability.

These sights are resistant to solvents, oils, and weathering—concerns that matter if your carry gun sees regular use, cleaning, and storage in variable conditions. The ML11517 set includes both front and rear blades fitted specifically for HK USP Compact dovetails and mounting, eliminating guesswork about compatibility. Meprolight backs the sights with a 12-year manufacturer warranty to the original owner, reflecting confidence in the tritium lifespan and construction.
