If you’re searching for AmeriGlo Sig Sauer night sights, a tritium sight set SG161, or green tritium sights with white outline for Sig, this set is engineered to provide the balance of visibility, durability, and classic three-dot style many shooters prefer.
Day & night performance with tritium illumination
Tritium sights are popular because they provide self-illuminated aiming references in low light—no batteries required. The AmeriGlo Classic SG161 uses green tritium in both the front and rear sights to support:
Clear sight references in dim indoor lighting
Better visibility during dawn/dusk conditions
Consistent “ready” capability without switches or charging
A reliable low-light solution for everyday carry and bedside setups
For shooters who want a practical low-light upgrade that stays “on” all the time, tritium is one of the most proven sight technologies available.
Green tritium + white outline: fast visibility in real conditions
This set pairs green tritium lamps with white outlines on both front and rear sights. That design choice matters because it supports two key goals:
Bright, recognizable sight picture in daylight
The white outlines help create strong contrast against common backgrounds, making the sights easier to pick up quickly during daytime practice and drills.
Strong low-light reference points
The green tritium provides a visible aiming reference when ambient light is limited, helping you maintain a consistent sight picture without relying on external illumination.
The result is a sight set that performs well across a wide range of lighting conditions—exactly what most shooters want from an all-purpose upgrade.
Classic Series sight picture: familiar and easy to learn
AmeriGlo’s Classic style is a favorite among shooters who want a straightforward, traditional sight picture that’s easy to train with and doesn’t require a learning curve. If you prefer a clean, no-nonsense approach—rather than oversized dots or specialty competition setups—the Classic layout is designed to feel intuitive and consistent.
This makes the SG161 a great fit for:
Newer shooters who want an easy-to-read setup
Experienced shooters who prefer traditional alignment
Carry and duty-style builds that prioritize clarity and reliability
Training pistols where consistent sight picture matters
Built for Sig Sauer pistols (SG161)
The SG161 is designed as a Sig Sauer-compatible sight set (confirm your specific model fitment before purchase). A proper-fit sight set matters because it ensures:
Correct alignment and point-of-aim consistency (when installed correctly)
A stable, secure fit in the slide dovetails
A professional, finished look that integrates with the pistol cleanly
Reliable performance through recoil and regular handling
For the best results, many shooters choose professional installation—especially if you don’t already have a sight pusher and experience with dovetail sights.

Upgrading your factory sights is one of the most meaningful changes you can make to a defensive or training pistol. The AmeriGlo Classic SG161 is a strong choice because it delivers:
Always-on tritium illumination without batteries
High-contrast white outlines for daylight speed
A classic sight picture that’s easy to learn and repeat
A brand reputation built around practical, serious-use sights
Whether your goal is better low-light capability or simply a clearer, more confidence-inspiring sight picture, this set provides a well-rounded improvement.
