Sig Sauer P220 .45 ACP Full Size 4.4" Nitron Stainless E2 Grip

The Sig Sauer P220 .45 ACP delivers proven single-action/double-action reliability in a full-size platform engineered for serious applications. This model combines the stopping power of .45 ACP with Sig's legendary Swiss-German engineering heritage. The Nitron-finished stainless steel slide provides enhanced corrosion resistance while maintaining the precision tolerances that make the P220 a trusted choice among law enforcement and competitive shooters.

What Makes This Different

The P220's single-stack magazine design creates a narrower grip profile compared to double-stack .45 ACP pistols, improving control and reducing printing for concealed carry despite its full-size frame. The E2 grip system reduces the trigger reach by approximately 1/4 inch, accommodating shooters with smaller hands without sacrificing the full-size benefits. Sig's proprietary Nitron coating penetrates the stainless steel surface, creating a finish that resists wear and corrosion better than standard bluing or parkerizing.

Key Features

• Single-action/double-action trigger system with decocking lever for safe carry
• 4.4-inch barrel with 1:16 twist rate optimized for .45 ACP ballistics
• 8+1 capacity single-stack magazine design for reliable feeding
• E2 grip reduces trigger reach by 0.25 inches from standard P220
• Nitron-finished stainless steel slide with black anodized aluminum frame
• Three-dot contrast sights with drift-adjustable rear sight
• Accessory rail accepts standard Picatinny-compatible lights and lasers

Field performance demonstrates consistent accuracy with quality .45 ACP ammunition, typically grouping within 2.5 inches at 25 yards from a rest. The full-size frame absorbs recoil effectively, enabling faster follow-up shots compared to compact .45 ACP pistols. Weather sealing around critical components maintains function in adverse conditions, while the stainless steel construction resists corrosion in humid environments or marine applications.
