Item # 288122 Style DFN-OA-2311-FPRO-ELT-HDB-PRT-21 UPC 850055310797 Condition New Manufacturer [OA Defense](https://www.kygunco.com/brand/oa-defense) Model OA 2311 Finish Tan Round Capacity 21 Caliber 9mm Action Semi-Auto Barrel Length 5 in The OA 2311 Pro is the full-size ported powerhouse of the OA Defense line-up. Designed and optimized for duty use and high round count range days, the OA 2311 Pro delivers maximum performance, accuracy, and reliability even under the harshest conditions. Integral V-porting in the 5″ barrel and slide reduce muzzle rise with minimal sight picture obstruction, even with +P self-defense ammunition. The Pro cut lightened slide profile increases cycle speed for faster follow-up shots and decrease split times. The enhanced Pro trigger treatment yields a slightly lighter trigger pull than the standard duty model triggers, facilitating an even smoother trigger break for increased accuracy and feel. With five magazines and four slide plates included in the kit, the OA 2311 Pro arrives with everything you need to maximize your performance. Proudly Made in America, OA Defense’s production and assembly process relies on precision engineering and machining, multiple rounds of stringent quality control, and a team of skilled techs and gunsmiths who work together to hand-fit and hand-finish the critical engagement points. Each assembled pistol then goes through a multi-point inspection and test firing process prior to being released for cleaning and shipping. - OA 2311™ Pro pistol with Black grip module - (5) 17/21-round Magpul AMAG® magazines - (4) Slide Plates – Iron sight cover plate; RMR, DPP, & Holosun K/RMSc footprint optic mounting plates - Night Fision tritium night sights (standard height installed; intermediate height for RMR optic plate; suppressor height front sight for use with DPP optic plate) Shop with KYGUNCO for the best selection, competitive pricing, and exceptional customer service.
