HI-VIS Fiber Front Sight STI

HI-VIS STI Fiber Optic Sights for 1911 & 2011 Pistols

Designed Specifically for STI 1911 and 2011 Platforms

Thunder Mountain Custom proudly offers the HI-VIS sight system engineered specifically for STI 1911 and 2011 handguns. From the start, these sights focus on speed, flexibility, and long-term durability. As a result, they deliver a clear advantage for competition shooters and serious enthusiasts alike.

Fast-Swap Fiber System for Maximum Flexibility

Change Sight Colors in Seconds

Instead of cutting, melting, and re-fitting fiber every time, the HI-VIS system lets you switch inserts instantly. Therefore, you can move from a target white dot to a red fiber, or then to a green fiber, in just seconds. Even better, you can reuse inserts repeatedly without damaging them or wasting material.

Simple, Tool-Assisted Installation

To change LitePipes, simply insert the included key between the LitePipe and spring. Then, slide the LitePipe out smoothly and replace it with your preferred option. Consequently, adjustments at the range or before a match become fast and frustration-free.

Precision Construction You Can Trust

Built to Rigid HI-VIS Standards

Every HI-VIS sight starts with premium materials and strict manufacturing tolerances. After machining, each sight undergoes shooter testing to ensure it holds up under real-world use. Because of this process, these sights consistently deliver long service life and dependable performance.

High-Visibility LitePipes

The LitePipes use a chemical-resistant, injection-molded material. As a result, they provide excellent brightness, resist wear, and maintain clarity over time. Additionally, HI-VIS backs this system with a one-year warranty for added confidence.

Performance-Driven Sight Design

Bright and Easy to Acquire

The sight body features a center cut that maximizes light gathering. At the same time, it retains structural strength for duty or competition use.

Precise Sight Picture

A square sight profile promotes consistent alignment with the rear sight. Consequently, shooters benefit from improved accuracy and faster target transitions.

Clear, Crisp Dot

The recessed LitePipe design eliminates halo effects. Therefore, the dot remains sharp and easy to focus on, even in bright conditions.

Reduced Glare and Smooth Draw

Ramped and serrated surfaces help cut glare. Meanwhile, carefully contoured edges keep the sight holster-friendly and snag-free.

Solid Steel Durability

Each sight base uses solid steel construction. As a result, it resists impact, wear, and hard use over time.

Factory-Correct Fit and Height

Designed to Match OEM Dimensions

HI-VIS machines each dovetail to original manufacturer specifications. Because factory sight height is maintained, these front sights pair perfectly with factory rear sights on STI pistols.
