SIG Sauer 1911 XO 45 ACP 5" Optics Ready 8-Round Black Pistol

The SIG Sauer 1911 XO delivers precision engineering in a classic platform enhanced with modern optics capability. This full-size 45 ACP pistol combines traditional 1911 reliability with contemporary features that serious shooters demand.

What Makes This Different

The optics-ready slide eliminates the need for expensive custom machining, accepting popular red dot sights directly from the factory. Unlike standard 1911s that require gunsmith modifications for optics mounting, this pistol ships ready for modern sighting systems. The enhanced trigger system provides a crisp 4.5-pound break with minimal overtravel, surpassing typical production 1911 triggers that often require aftermarket upgrades.

Key Features

• Optics-ready slide cut accepts Shield RMSc footprint red dot sights
• Stainless steel barrel with target crown for enhanced accuracy
• Low-profile combat sights co-witness with mounted optics
• Beveled magazine well for faster reloads under stress
• Checkered G10 grips provide secure purchase in wet conditions

Range performance centers on the match-grade barrel that consistently delivers sub-2-inch groups at 25 yards with quality ammunition. The enhanced trigger system enables precise shot placement in competitive shooting scenarios, while the robust construction handles +P ammunition without reliability concerns. Weather-resistant finish maintains function in adverse conditions, making this suitable for duty carry or home defense applications.
