Cammer™ .404″ 1911 Sear – Neutral Engagement

Cammer™ .404″ 1911 Sear – True Neutral Engagement Trigger Control

The Cammer™ .404″ Sear delivers a truly neutral trigger release for the 1911 platform. Unlike traditional sears, this design maintains a constant .404-inch distance from the sear pin center, which keeps hammer engagement neutral throughout the entire release cycle. As a result, the trigger movement feels smooth, controlled, and nearly undetectable to the shooter’s finger.

CNC machined by Evolution Gun Works (EGW) for Cammer Technologies, this sear installs easily and eliminates the need for complex stoning techniques or expensive jigs.

True Neutral Engagement by Design

Most conventional 1911 sears rely on flat primary and secondary angles. Because of this, they move in an arc beneath the hammer hooks. Consequently, they become either positive (lifting the hammer) or negative (dropping the hammer) during release.

In contrast, the Cammer™ .404″ Sear maintains neutral engagement from start to finish. The hammer neither rises nor falls as the sear moves. Therefore, the release remains consistent and predictable.

This neutral relationship works equally well with hammer hooks cut at 86 or 90 degrees, providing flexibility without compromising feel.

Smooth Trigger Pull Without Specialized Stoning

Because the Cammer™ sear geometry controls engagement naturally, there is no need for secondary or release angles. As a result, you can achieve a refined trigger pull without advanced stoning skills.

Even so, experienced pistol smiths may still add custom angles if desired. However, the sear performs exceptionally well right out of the package.

Consistent Release You Can Feel—or Not Feel

All 1911 sear and hammer systems require movement to release. The goal, however, is movement that the shooter cannot detect. The Cammer™ .404″ Sear achieves exactly that.

Instead of transitioning between positive and negative engagement, this sear relies on:

• Friction

• Sear spring tension

Together, these forces hold the sear securely until release, producing a clean, smooth trigger pull that feels the same shot after shot.

Gunsmith-Tunable Variables

While the sear geometry remains fixed, skilled pistol smiths can fine-tune overall trigger feel by adjusting:

• Hammer hook height

• Surface smoothness

• Sear spring tension

• Main spring weight

Because of this, the Cammer™ .404″ Sear works equally well in factory pistols, custom builds, and competition guns.

Precision Manufacturing You Can Trust

Evolution Gun Works machines each Cammer™ sear using CNC processes for exceptional consistency and accuracy. In addition, the sear meets U.S. Ordnance specifications, which call for a sear length of .4045″ ± .003″.

As a result, this sear installs cleanly and performs reliably in standard 1911 pistols.
