The AmeriGlo SG161 is a tritium night sight set purpose-built for Sig Sauer pistols, designed for shooters who need reliable target acquisition in low light or no-light conditions. This #8 front and rear sight pairing combines green tritium tubes with white outline rings, giving you both fast glow-in-the-dark capability and a visible sight picture in daylight. Whether you're carrying for self-defense, running night qualifications at the range, or training in variable lighting, tritium sights eliminate dependence on ambient light or a flashlight to align your shot.
Tritium night sights work without batteries—the radioactive isotope continuously glows for years of service life, making them ideal for defensive pistols where reliability matters most. The green tritium paired with white outline design strikes a balance: the tritium provides that glow when darkness falls, while the white ring keeps you oriented in daylight without the clutter of three-dot geometry. AmeriGlo's Classic line is known for clean, straightforward sight pictures that won't slow you down in a fight.
These sights are a direct fit for compatible Sig Sauer pistol models, so installation is straightforward if you have basic armorer knowledge—or you can have them installed by a qualified gunsmith. Because they're tritium, they'll keep working whether you practice weekly or carry for years between range sessions.

Frequently Asked Questions
What Sig Sauer pistols are compatible with the AmeriGlo SG161?
The SG161 is designed for Sig Sauer pistols that accept standard tritium sight dovetails. Confirm your specific model with a gunsmith or Sig dealer before ordering, as sight compatibility varies by platform. Most modern Sig duty and compact models will accept these sights with proper installation.
Do tritium sights work without a flashlight or batteries?
Yes. Tritium sights are self-illuminating—the tritium isotope glows continuously without requiring batteries or external light. This makes them ideal for defensive carry and training scenarios where you need sights you can trust in any condition.
What's included in the SG161 sight set?
The SG161 is a two-piece set: one #8 front sight and one #8 rear sight, both with green tritium and white outline rings. Installation hardware and gunsmithing may be required depending on your pistol and experience level.
How long do tritium sights stay bright?
Tritium has a half-life of approximately 12.3 years, meaning the sights will remain usefully bright for a decade or more of normal carry and use. After many years, the glow gradually diminishes but doesn't suddenly fail.
