Kimber Mfg.,inc 4000939 1911 Trijicon RMR Optic Plate White Dot Rear Sight

The Kimber Mfg., Inc. 4000939 1911 Trijicon RMR Optic Plate with White Dot Rear Sight is a precision-engineered mounting solution designed for 1911 platform users who demand modern optic capability without sacrificing proven ergonomics. This adapter plate bridges the gap between classic 1911 geometry and contemporary red-dot technology, enabling operators to mount Trijicon RMR reflex sights while maintaining the traditional white dot rear sight reference. Built for duty-rated reliability, this Kimber accessory serves law enforcement, military, and civilian tacticians seeking improved target acquisition speed and accuracy under dynamic shooting conditions.

The Kimber 4000939 optic plate features precision-machined construction that ensures repeatable zero retention and co-witness capability with the integrated white dot rear sight, delivering both backup aiming reference and rapid primary optic indexing. The mounting system is engineered to minimize stack height and lateral offset, critical for maintaining 1911 balance and draw ergonomics from concealed or duty rigs. Trijicon RMR compatibility provides unlimited eye relief and proven durability in adverse environments—a combination that has earned trust across tactical teams and armed professionals who operate in low-light, high-stress scenarios where split-second target confirmation determines mission outcome.

This mounting plate is fully compatible with Kimber 1911 slide cuts and RMR-configured firearms, making it an ideal upgrade for shooters transitioning existing platforms to optics-ready configuration. Installation requires no permanent slide modification when used on pre-cut Kimber models, and the white dot rear sight ensures zero loss of defensive capability during optic failure. Whether mounted on a custom defensive 1911, duty weapon, or competition platform, the Kimber 4000939 delivers the durability and precision demanded by professional users while maintaining the proven reliability that has defined the 1911 platform for over a century.
