The OA Defense 2311 Compact with Plus Kit (brand part no. 2311COMPACTSTPBLK) takes the same disciplined 2311 platform engineering and adds a taller magwell for a full 17+1 capacity in 9mm without giving up the compact frame’s concealability. A stainless steel barrel and precision-tuned internals keep the pistol running consistently, while the Plus Kit’s extended aluminum magwell and matching magazines add capacity with minimal added bulk. Fully ambidextrous controls and an optics-ready, serrated slide round out a pistol built for everyday carry and duty-grade personal defense alike. The upgraded G2 hammer and sear system gives it a clean, repeatable trigger break.
