Heavy Duty Firing Pin Spring

The Heavy Duty Firing Pin Spring by Nowlin is a precision replacement component engineered for shooters who demand reliable ignition performance in their 1911 platform pistols. Built to exacting standards, this heavy duty firing pin spring restores factory-spec tension and ensures consistent hammer-to-primer strikes across Government, Commander, and Officers models. Whether you're maintaining a tactical duty weapon, competition shooter, or heirloom 1911, a worn firing pin spring is one of the most overlooked maintenance items—yet critical to safe, reliable function.

Manufactured to Nowlin's rigorous specifications, this heavy duty spring delivers the correct preload pressure needed to control firing pin protrusion and prevent light strikes or slamfires. The spring's material composition and temper are designed to resist fatigue and maintain tension through thousands of firing cycles, outlasting standard springs commonly found in decades-old pistols. Proper firing pin spring tension is essential for reliable primer ignition, especially in defensive scenarios where feed reliability is non-negotiable. The compact, featherweight design (0.01 lbs) ensures no impact on pistol balance or handling characteristics.

This replacement spring is ideal for gunsmiths, armorer's rebuilding 1911 platform firearms, and individual owners performing preventive maintenance on their pistols. Compatible across all major 1911 variants—including the full-size Government model, compact Commander, and subcompact Officers—the heavy duty firing pin spring integrates seamlessly during standard field stripping and reassembly. Installation requires no special tools and typically takes less than five minutes as part of routine maintenance or complete trigger group service. For shooters seeking to restore or upgrade aging 1911 reliability, this precision component delivers measurable improvement in ignition consistency and long-term durability.
