Outdoor Arms OA-2311 FPRO 9mm Pistol Kit w/ HDB Barrel 21rd

The Outdoor Arms OA-2311-FPRO delivers precision engineering in a competition-ready 9mm platform designed for serious shooters. This complete kit configuration includes the HDB (Heavy Duty Barrel) system and high-capacity magazine setup for extended range sessions and competitive applications.

What Makes This Different

The FPRO series incorporates a match-grade trigger system and enhanced slide geometry that reduces muzzle flip by approximately 15% compared to standard 1911-style platforms. The HDB barrel features a proprietary rifling pattern with a 1:10 twist rate optimized for 115-147 grain projectiles. Unlike traditional 1911 designs, this platform accepts double-stack magazines while maintaining the familiar grip angle and manual of arms.

Key Features

• Match-grade HDB barrel with enhanced rifling for consistent accuracy
• 21-round primary magazine with 17-round backup included
• Competition-tuned trigger with crisp break and short reset
• Ambidextrous safety controls for left and right-handed shooters
• Picatinny rail section for optics and tactical accessories
• Enhanced slide serrations for positive grip in adverse conditions
• Nitride-finished internal components for corrosion resistance

Field testing demonstrates consistent 2.5-inch groups at 25 yards with quality ammunition. The platform excels in USPSA Production division competition where the higher capacity provides a tactical advantage. Law enforcement agencies have adopted similar configurations for duty use due to the reliability record and familiar manual of arms. The HDB barrel system maintains accuracy through extended firing schedules without degradation.
