Visual Excellence Meets Functional Precision

The Gun Engineer Spectrum Recoil Spring Plug introduces a dynamic visual element to your 1911 platform without compromising operational integrity. Its multi-color PVD coating creates a striking iridescent effect that resists holster wear and environmental exposure, making it ideal for custom builds and competitive displays. Beyond aesthetics, this component maintains exact tolerances to ensure smooth recoil spring operation and prevent binding during rapid fire.

Constructed from high-grade 4140 steel and enhanced with advanced Physical Vapor Deposition technology, it delivers exceptional corrosion resistance and surface hardness, outperforming traditional finishes in durability and visual appeal.

Distinctive Design Attributes:

• Multi-Color PVD Coating – Iridescent spectrum finish for unique visual depth and scratch resistance
• 4140 Steel Substrate – High-tensile material provides impact strength and longevity
• Precision CNC Machining – Tight tolerances within ±0.0005″ for flawless fit and function
• Optimized Spring Interface – Polished inner bore reduces friction and wear on recoil springs
• Tool-Less Installation – Simple drop-in design for quick upgrades without gunsmithing
• Enhanced Surface Hardness – PVD layer achieves 80HRc for superior abrasion resistance
