The strut (or hammer strut) is a small but vital link in the 1911 and 2011 fire control system. It connects the hammer to the mainspring cap, transmitting the mainspring's force to the hammer. A high-quality, properly fitted strut ensures smooth, consistent hammer movement, contributing to reliable ignition and overall trigger performance. For competitive shooters, a durable strut helps maintain a consistent trigger pull and prevents binding.

The Unsung Link in Your Ignition System

An optimized strut contributes to overall reliability and trigger feel:

  • Efficient Power Transfer: Transfers mainspring energy to the hammer, ensuring consistent primer ignition.

  • Smooth Hammer Movement: A polished, precisely dimensioned strut moves freely, preventing friction or binding that causes inconsistent hammer fall or trigger pull.

  • Durability and Longevity: Made from hardened, high-quality steel, it resists wear and bending over thousands of cycles.

  • Consistency for Tuning: Ensures smooth, predictable mainspring force application, crucial for a refined trigger feel.

Shooters Connection offers a range of high-quality struts for both 1911 and 2011 platforms, crafted for precise fit and lasting durability.

Choosing Your 1911 / 2011 Strut

When selecting a strut, focus on material quality and dimensional consistency:

  • Material: Look for hardened steel (tool or stainless) for maximum strength and wear resistance.

  • Finish: A smooth, polished finish reduces friction.

  • Dimensional Accuracy: Ensure pin holes and overall length are within tight tolerances for proper fit.

Struts are generally considered drop-in parts. Replace it if it shows signs of bending, excessive wear, or rough surfaces, as a damaged strut can lead to inconsistent hammer fall or light primer strikes. Struts are highly standardized across most 1911 and 2011 models.
