AO Defense 2311 Compact Pro Plus-Kit 9mm 4.25" DLC/Aluminum 17+1 Semi-Auto Pistol with Night Sights
The AO Defense 2311 Compact Pro Plus-Kit blends a familiar 1911-style single-action trigger with modern SIG P320 magazine compatibility, giving shooters a crisp break and generous 17-round capacity in a carry-sized frame. A black DLC-finished slide with lightening window, ambidextrous controls, and factory night sights make this recent-release pistol a turnkey defensive package.

- Streamlight TLR-X weapon light

The 2311 Compact pairs a 4.25-inch 416 stainless barrel with a DLC coating for long-term corrosion resistance and easy cleaning. Its link-less cam-slot lockup simplifies takedown while maintaining accuracy.
A 7075-T6 aluminum frame keeps weight manageable, and the OA-Gray polymer grip module features aggressive texturing, molded gas-pedal thumb rests, fully ambidextrous slide-stop levers, and a Plus-Kit flared magwell. The extended magwell accepts the included 17-round magazines; the 15-round magazines currently do not seat flush due to the grip extension.
The flat-faced single-action trigger, skeletonized hammer, and reversible triangular magazine release provide a crisp, customizable shooting experience. Ambidextrous thumb safeties and Night Fision tritium sights (orange-outline front, U-notch rear) support confident control in low-light conditions.
Forward and rear cocking serrations, an optic plate cut, and a lightening window on the slide add both function and modern styling. A full-length accessory rail seamlessly accommodates the included Streamlight TLR-X.
