Rock Island Armory 1911 GI 10mm 8+1 5" Optic Ready Pistol

The Rock Island Armory 57180 GI delivers serious 10mm power in a proven 1911 platform designed for shooters who demand reliable performance without compromise. This full-size pistol combines traditional 1911 craftsmanship with modern features like optic-ready capability and enhanced grip texture.

What Makes This Different

Unlike standard .45 ACP 1911s, this model chambers the potent 10mm Auto cartridge, delivering significantly more energy downrange while maintaining the classic 1911 manual of arms. The optic-cut slide accepts popular red dot sights without requiring additional machining, while the serrated slide surface provides enhanced grip during manipulation. The steel construction throughout ensures durability under heavy use that polymer alternatives cannot match.

Key Features

• 10mm Auto chambering provides superior ballistic performance over traditional .45 ACP
• Optic-ready slide cut accommodates popular red dot sight systems
• 8+1 capacity with single-stack magazine design
• 5-inch steel barrel with matte black finish resists corrosion
• Serrated slide surfaces improve grip during press checks and malfunction clearing
• Black rubber grip panels enhance control during recoil management
• All-steel frame and slide construction for maximum durability

The 10mm chambering makes this pistol particularly effective for hunting medium game, competitive shooting, and situations requiring maximum stopping power. The full-size 5-inch barrel extracts maximum velocity from 10mm loads while the steel frame absorbs recoil effectively. Weather resistance comes from the matte black finish that protects against moisture and handling wear.
