TMC Mainspring Housing Retainer – Blued

1911 / 2011 Mainspring Housing Retainer – Carbon Steel, Blued

Restore Secure Retention, Proper Alignment, and Proven Reliability

The 1911 / 2011 Mainspring Housing Retainer – Carbon Steel, Blued delivers a precision-machined replacement that, first and foremost, secures the mainspring housing with consistent and dependable retention. Moreover, this component is manufactured from high-grade carbon steel and finished with a durable black oxide coating, which ensures proper fitment, increased strength, and long-term reliability. As a result, your pistol maintains predictable internal function across duty, carry, and competition use.

Over time, factory mainspring housing retainers frequently wear, bend, or loosen. Consequently, spring alignment suffers, tension becomes inconsistent, and overall reliability declines. However, this hardened carbon steel retainer directly addresses those problems. By restoring correct geometry and structural integrity, it reestablishes secure retention. In turn, internal components remain aligned, stable, and consistent during operation.

Precision Swiss CNC Manufacturing

Exact Dimensions for Consistent Fit and Function

Each 1911 / 2011 mainspring housing retainer begins as premium carbon steel stock and is machined on advanced Swiss CNC screw machines for exact dimensional control. Furthermore, once machining is complete, every retainer proceeds through a tightly controlled finishing process that includes:

• Centerless grinding to achieve precise diameter accuracy

• Full heat treatment and hardening to increase strength and wear resistance

• Black oxide bluing to enhance corrosion resistance and surface durability

• Final surface finishing to ensure smooth installation and reliable engagement

Because of this meticulous manufacturing process, the retainer installs cleanly and locks into place securely. Therefore, it remains stable under recoil while maintaining proper function through extended firing cycles.

Built for Strength and Long-Term Reliability

Hardened Carbon Steel for Demanding Use

Unlike softer factory retainers, this hardened carbon steel component resists bending, deformation, and loosening under recoil. Consequently, it maintains proper mainspring alignment while preventing unwanted movement. At the same time, it supports consistent ignition and dependable hammer operation.

Additionally, the hardened steel construction withstands high-round-count use without premature wear. As a result, it not only restores current performance but also helps extend the service life of surrounding internal components and frame contact points.

All components meet or exceed manufacturer specifications. Therefore, they deliver dependable performance in duty pistols, competition builds, and custom firearms alike.
