Extreme Engineering 1911 Sear – Extreme Duty

Extreme Engineering 1911 Sear – Extreme Duty

This 1911 Sear Provide Tactical Strength with Smooth, Controlled Trigger Feel

The Extreme Engineering 1911 Sear – Extreme Duty delivers maximum strength, reliability, and control for shooters who demand the finest tactical sear available. Extreme Engineering designed this sear for hard-use pistols where durability and consistent engagement matter above all else. As a result, it performs exceptionally well in duty, tactical, and high-round-count 1911 builds.

Aerospace Steel Construction for Extreme Strength

Extreme Engineering machines the Extreme Duty Sear from the same aerospace-grade steel alloy used in their premium hammers. In addition, this sear uses the same special die steel found in the Ultra Match Sear. This material provides outstanding mechanical strength, with a tensile strength of 265 KSI and a yield strength of 245 KSI.

Because of this steel choice, the sear resists deformation and wear even under heavy use. Consequently, it maintains precise geometry and dependable engagement over a long service life.

Heat Treated for Reliability and Longevity

Extreme Engineering heat treats the Extreme Duty Sear to Rockwell C 50–53, striking the ideal balance between toughness and wear resistance. This heat range ensures strong engagement surfaces while still allowing smooth, predictable movement. Therefore, the sear delivers consistent performance without becoming brittle or prone to premature wear.

Heavy-Duty Profile with Optimized Sear Legs

The Extreme Duty Sear uses the same heavy-duty, full-profile body as the Extreme Engineering Tactical Sear. However, Extreme Engineering redesigned the sear legs using the contour found on the Ultra Match Sear. This refined shape creates a radiused contact point where the sear meets the sear spring.

Because of this radiused contact surface, the sear moves against the spring with less friction. As a result, the sear cycles more smoothly and moves faster during the cocking cycle.

Faster Sear Movement, Better Engagement

The increased sear speed during cocking allows more positive engagement with the hammer. At the same time, the smoother movement against the sear spring improves overall trigger feel. Consequently, shooters experience a cleaner, more controlled trigger pull without sacrificing strength or safety.

This balance of speed, strength, and smoothness makes the Extreme Duty Sear ideal for tactical pistols that require both reliability and refined trigger control.
