Wilson Combat 423S Ambidextrous Thumb Safety High Ride 1911 Stainless

The Wilson Combat 423S Thumb Safety transforms standard 1911 pistols with precision-engineered ambidextrous controls that accommodate both left and right-handed shooters. This high-ride design positions the safety lever for optimal thumb placement while maintaining the classic 1911 profile.

What Makes This Different

Unlike factory thumb safeties that favor right-handed operation, the 423S features symmetrical engagement surfaces machined to exact tolerances. The high-ride configuration reduces the distance your thumb travels to disengage the safety, cutting reaction time by approximately 0.2 seconds compared to standard-height alternatives. Wilson Combat's proprietary heat treatment process ensures consistent engagement pressure across thousands of activation cycles.

Key Features

• Ambidextrous operation with identical left and right-side lever geometry
• High-ride positioning for faster thumb access and reduced travel distance
• 416 stainless steel construction with corrosion-resistant finish
• Precision-fit design requires minimal gunsmith fitting on most 1911 frames
• Maintains proper half-cock notch engagement for safe carry
• Compatible with standard 1911 Government and Commander frame sizes
• Checkered contact surfaces prevent thumb slippage during manipulation

Competitive shooters report improved stage times when transitioning from holster to first shot, particularly in USPSA and IDPA divisions where manual safeties are required. The stainless steel construction resists wear from repeated use and environmental exposure, maintaining crisp engagement even after extended range sessions. Law enforcement agencies have adopted this configuration for officers who require ambidextrous controls without compromising the familiar 1911 manual of arms.
