Ruger American Trigger Spring

Description

Ruger American Trigger Spring

This spring is a replacement for the trigger pull spring of a Ruger American rifle. It reduces the minimum trigger weight of the trigger from ~1450g to ~960g (~3,2lb to ~2,1lb), or approx. 34% (the exact value is dependent on the individual firearm). It works for both centrefire and rimfire models of the Ruger American.

A simple way to estimate the trigger weight you might achieve, is to measure the minimum trigger weight of your firearm, and multiply the value by 0,66. It doesn’t work for all firearms, but for most it gets you in the ballpark. Example: 1730 g * 0,66 = 1142 g

Manufacturing and Performance Characteristics

Most commercially available trigger springs are general‑purpose industrial components with uneven end surfaces, variable coil counts and measurable batch‑to‑batch variation. These factors introduce lateral friction (“spring drag”) and contribute to inconsistent trigger pull weights.

Insimbi Outdoor springs are custom‑ordered to specification, with controlled geometry and consistent material properties:

• Closed and ground ends to ensure linear, friction‑stable compression
• Fixed coil geometry for predictable and repeatable pull weights
• 1.4310 / X10CrNi18-8 stainless steel for corrosion resistance and long‑term dimensional stability
• Manufactured in Germany to tight tolerances for uniformity across production batches

This controlled production approach reduces the variability associated with mass‑produced industrial springs and supports a consistent, uniform trigger break.

For additional improvement, you can also install our Ruger American Trigger Shims.

These reduce side‑to‑side play between the trigger and housing, which can smooth out the trigger pull and in some rifles, provide a small further reduction in trigger weight. They work on both rimfire and centrefire Ruger American models and pair well with this spring for the best overall result.

Insimbi Outdoor springs are built for long‑term reliability. If anything fails due to material or manufacturing defects, we’ll replace it.

Disclaimers

Not compatible with the Ruger Precision Rifle.

Spring should only be installed by a qualified gunsmith.

The trigger weight of your individual firearm can vary by up to +- 450g (+- ~1,0lb) or more compared to the value published. This is due to the manufacturing tolerances of the firearm. For more information on this, see our FAQ page.
