TMC Government 1911 Hammer Spring / Mainspring – 19 Pounds

The TMC 19‑Pound Government 1911 Hammer Spring / Mainspring gives your 1911 a lighter, smoother trigger pull. By reducing tension compared to the factory 23-pound spring, it creates a softer, more responsive break. As a result, your pistol feels more controlled and comfortable while maintaining reliable hammer performance.

Balanced Trigger Pull

Hammer springs play a key role in trigger feel. A lighter spring reduces pull weight, while a heavier spring increases hammer force. This 19-pound spring provides a balanced, lighter pull without sacrificing consistent ignition. Additionally, TMC offers multiple spring weights, so you can fine-tune your 1911 for your personal preference. Therefore, this spring is ideal for shooters seeking a softer, smoother trigger action.

Durable and Reliable Construction

TMC manufactures each spring from strong, American-made spring steel. As a result, it resists fatigue and holds its shape through thousands of compression cycles. Furthermore, it fits securely inside the mainspring housing, which ensures predictable hammer control and reliable operation shot after shot.

Easy Installation

Replacing the hammer spring requires disassembly and reassembly of the mainspring housing. While experienced shooters can install it with basic tools, basic gunsmithing knowledge is recommended. Once installed, the spring immediately improves trigger feel and maintains consistent hammer tension.
