Sig Sauer P229 M11-A1 9mm 3.9" Barrel 10+1 Capacity Pistol

The Sig Sauer P229 M11-A1 delivers military-proven reliability in a compact duty pistol configuration. This 9mm Luger platform combines the proven P229 operating system with enhanced ergonomics and reduced capacity for restricted markets.

What Makes This Different

The M11-A1 variant incorporates specific military contract improvements over standard P229 models. The black hardcoat anodized aluminum frame provides superior corrosion resistance compared to standard finishes while maintaining the lightweight characteristics essential for extended carry. The serrated Black Nitron stainless steel slide offers enhanced grip surface and weather protection that exceeds conventional bluing or parkerizing treatments.

Key Features

• Black Nitron stainless steel slide with anti-glare serrations for positive manipulation
• Hardcoat anodized aluminum frame reduces weight while increasing durability
• 3.90-inch barrel length optimizes velocity and accuracy in compact format
• 10+1 capacity with flush-fitting magazine for concealed carry applications
• Enhanced polymer grip panels provide improved texture and control

Field performance demonstrates consistent accuracy with various 9mm ammunition weights from 115 to 147 grains. The DA/SA trigger system provides tactical flexibility for duty and defensive applications. The Nitron coating resists environmental corrosion in humid conditions while the aluminum frame maintains structural integrity through extended firing schedules.
