TMC Government 1911 Hammer Spring / Mainspring – 17 Pounds

The TMC 17‑Pound Government 1911 Hammer Spring / Mainspring gives your 1911 a lighter and smoother trigger feel while still keeping dependable hammer tension. Because TMC uses high‑quality, American‑made spring steel, this spring delivers consistent performance, reliable ignition, and long‑lasting durability. As a result, your pistol runs smoothly and feels more responsive during every shot.

Lighter Trigger Pull with Reliable Ignition

A 17‑pound hammer spring offers a noticeable reduction in trigger pull compared to the factory 23‑pound spring. Therefore, it is a great choice for shooters who want a cleaner, lighter break without sacrificing reliability. This weight works well with many competition and range setups, especially when paired with properly tuned ignition components. Additionally, the reduced tension still provides enough hammer force for consistent primer ignition with most quality ammunition.

Great Option for Tuning and Custom Builds

Hammer springs play an important role in the overall feel of your 1911. For example, lighter springs reduce trigger weight, while heavier springs increase hammer force. Since the 17‑pound spring sits on the lighter side of the tuning range, it offers a smooth, easy trigger pull that many shooters prefer. Moreover, TMC offers several spring weights, so you can fine‑tune your pistol even further. As a result, tuning becomes simple, accurate, and consistent.

Durable and Long‑Lasting Construction

TMC forms each hammer spring from strong, heat‑treated American spring steel. Because of this, the spring resists fatigue and maintains tension through thousands of cycles. In addition, it fits securely inside the mainspring housing. Consequently, you get stable hammer movement, smooth operation, and predictable performance every time you pull the trigger.

Straightforward Installation

Installing the hammer spring requires basic disassembly and reassembly of the mainspring housing. While many shooters can complete the job with simple tools, basic gunsmithing knowledge is recommended. Once installed, the spring delivers a lighter, cleaner trigger pull and a more refined shooting experience.
