Wolff Spring – Colt 1911 CMMDR Standard
- Refine your trigger control and ignition reliability with Wolff Hammer Springs, expertly engineered for the legendary Colt 1911 platform. Designed to meet or exceed factory specifications, these springs provide precision-driven performance upgrades for a wide range of 1911 models, including the Colt 1911, 1911A1, 1991, Government, MKIV, Gold Cup, and Commander variants, and are compatible with calibers such as .45 ACP, Super .38, 9mm, and 10mm Auto (Delta Elite).
- The Wolff 23lb Hammer Spring (also known as the mainspring) is the factory-standard weight and serves as a direct replacement for worn or weakened original springs. Its consistent resistance ensures reliable primer ignition, crisp hammer release, and safe, repeatable operation under a wide range of shooting conditions.
- Wolff hammer springs are made from premium-grade high-tensile spring steel, heat-treated and stress-relieved for long-term durability and sustained performance even under high round counts and demanding use. Whether you’re restoring a classic sidearm, maintaining a duty pistol, or customizing a competition-ready build, this spring ensures dependable hammer function and consistent trigger feel.
- For shooters looking to optimize their trigger pull characteristics or tailor their pistol to specific ammunition loads, Wolff offers a variety of hammer spring weights, allowing for reduced let-off pressure or enhanced ignition force. Lighter hammer springs can help produce a smoother, lighter trigger pull, while heavier springs maintain harder hammer strikes for more consistent ignition with tougher primers.
- If you’re experimenting with trigger tuning or unsure which spring weight best suits your setup, the Wolff Hammer Spring Pak is the ideal solution. Each kit includes multiple spring weights, making it easy to test and dial in the perfect balance of performance and feel.
