Main Spring Housings 1911 / 2011

The main spring housing (MSH) is a critical 1911 or 2011 component, simultaneously encasing the mainspring assembly and forming the rear of your grip. For competitive shooters, a quality MSH ensures consistent mainspring function, provides fire control stability, and offers vital ergonomic customization for optimal grip and recoil control.

Impact & Selection

An optimized MSH significantly boosts performance and feel:

  • Mainspring Encapsulation: Securely houses the mainspring, ensuring consistent hammer energy and reliable ignition.

  • Ergonomic Customization: Forms the grip's rear strap, available in various shapes (flat, arched) and textures (checkered, serrated) to tailor grip for comfort and control.

  • Stable Foundation: Precisely positions the mainspring assembly, preventing play that could impact trigger pull.

  • Durability & Aesthetics: Built from robust materials like steel, aluminum, or polymer, enhancing your pistol's look.

Shooters Connection offers diverse MSHs for 1911 and 2011 platforms, letting you fine-tune mechanics and ergonomics.

Consider Shape (Flat vs. Arched), Material (Steel for weight, Aluminum/Polymer for lightness), Texturing for grip, and Compatibility with your specific frame. (Note: 2011s usually have integrated MSHs).

Replacing an MSH is generally straightforward. A poorly fitting MSH can indirectly affect trigger pull consistency. A heavier MSH can subtly alter balance and perceived recoil. Ergonomic changes also influence recoil management. MSH changes are standard and accepted in virtually all competition divisions.
