Ameriglo CAP Tritium Night Sights for S&W M&P Shield / Front Tritium – Green / Front Outline – LumiGreen / Style – CAP / Rear Paint Bar – LumiGreen

Night sights built for M&P Shield carry pistols need to perform when ambient light fails. Ameriglo's CAP tritium design delivers a green front sight paired with LumiGreen outlines for fast target acquisition in darkness. Whether you're training near San Francisco or carrying daily, upgrading your factory sights makes a measurable difference. TacticCAL handles FFL transfer in Sunnyvale for all optics and sight packages.

Tritium brightness and paint bar contrast

Tritium self-illuminates without batteries or activation, making these sights reliable in complete darkness. The green tritium front sight pairs with a LumiGreen rear paint bar that absorbs ambient light and glows in low conditions. This combination creates a fast sight picture whether you're shooting in daylight or low-light scenarios.
