OA Defense 2311 Compact Pro 9mm 15rd 4.25" Ported Optic Ready

The OA Defense 2311 Compact Pro delivers competition-grade performance in a carry-friendly package with its ported 4.25-inch barrel and optic-ready slide configuration. This striker-fired pistol combines the reliability of proven 1911-style ergonomics with modern manufacturing precision and enhanced features for serious shooters.

What Makes This Different

The 17-4 stainless steel slide construction provides exceptional durability while maintaining lighter weight compared to traditional carbon steel alternatives. Factory porting reduces muzzle rise by approximately 15-20% during rapid fire sequences, while the optic-ready slide accepts popular red dot sights without additional machining. The ambidextrous controls accommodate both right and left-handed shooters equally.

Key Features

• Ported 4.25-inch barrel with black DLC coating for enhanced corrosion resistance
• 17-4 stainless steel slide with gray/black finish and integrated optic mounting plate
• 15-round capacity magazine with extended base pad
• Ambidextrous safety and slide release controls
• Polymer grip frame with aggressive texturing for secure handling
• Match-grade trigger system with crisp break and short reset
• Low-profile three-dot sight system co-witnesses with mounted optics

Range testing demonstrates consistent 2.5-inch groups at 25 yards with quality ammunition. The ported barrel design maintains sight picture during rapid strings while reducing felt recoil by approximately 10-15%. USPSA and IDPA competitors appreciate the balanced weight distribution and natural point of aim. The pistol functions reliably with both 115-grain and 147-grain 9mm loads across temperature ranges from -10°F to 140°F.
