OA Defense 2311 Full Size 9mm Luger 17+1 5" Semi-Auto Pistol

The OA Defense 2311 Full Size is a 2011-pattern duty pistol chambered in 9mm Luger with a 17+1 capacity. Built on the modular 2011/1911 architecture, this full-size platform is designed for duty, home defense, and range use, pairing modern features with the slim double-stack grip profile and single-action trigger that define the 2011 format.

At its core, the 2311 Full Size pairs a 5" stainless steel barrel with a black steel optic-ready slide finished with serrations for easy press checks and manipulations. The slide is cut to accept a red dot optic, giving shooters a turnkey host for pistol-mounted optics right out of the box. The frame is precision-machined from black aluminum with an integrated Picatinny accessory rail under the dust cover for mounting weapon lights or lasers, while the black polymer grips keep the overall package light at roughly 29 oz unloaded.

The single-action trigger is tuned for a clean 4.0 - 4.5 lb pull, and the controls are fully ambidextrous - including the thumb safety - making this pistol equally comfortable for right- and left-handed shooters. The double-stack 17-round magazine keeps capacity competitive with full-size duty 9mm pistols while retaining the slim 2011 grip profile that the platform is known for.

Whether you're building out a duty rotation, an optics-ready home-defense handgun, or a range-ready 9mm pistol, the OA Defense 2311 Full Size is a modern, modular 2011 platform ready to run.
