Built for Smooth, Reliable Operation

Many factory disconnectors use soft steel or stamped parts. Over time, those parts wear down. Because of that, trigger feel often suffers.

In contrast, Thunder Mountain Custom machines this 1911 disconnector from premium S-7 tool steel. This material resists impact, stress, and wear. Therefore, the part holds its shape even after heavy use.

After machining, each disconnector goes through heat treatment. Then, Thunder Mountain Custom polishes the slide notch and sear spring contact areas. As a result, friction drops and movement becomes smoother. At the same time, the part keeps its exact dimensions.

Because the shape stays true, the disconnector cycles smoothly and resets consistently.

Drop-In Fit With a Crisp Trigger Break

Because the engagement surfaces arrive polished, this disconnector usually drops straight into most Series 70-style 1911 pistols. In most cases, no fitting is needed.

As a result, shooters notice a clean, sharp trigger break right away. Many describe it as a “breaking-glass” feel. In addition, the reset feels more positive and predictable.

Whether you are refreshing an older pistol or building a match gun, this disconnector delivers fast and noticeable improvement.
