Shadow Systems Axio Features The Shadow Systems Axio is built around a heavy-duty precision-machined steel chassis that places mass exactly where it belongs delivering exceptional balance and a precise slide-to-frame fit. This architecture defines how the pistol shoots how it returns to target and how confidently it runs under real-world use. The 4.4 octagon barrel is chambered in 9mm Luger with a 1:10 twist feeding from Glock-compatible magazines with an 18+1 capacity. The Next-Gen trigger breaks between 4.5 and 5 lb giving the shooter a consistent predictable pull for precise shot placement and the octagon barrel profile adds rigidity that supports accuracy shot after shot. An interchangeable backstrap grip lets shooters adjust the fit of the polymer grip panels to their hand size and ambidextrous controls support operation from either side of the pistol regardless of the shooter s dominant hand. Green tritium front and black serrated rear sights give the shooter a fast high-contrast sight picture in low light backing up the optic cut for shooters who prefer iron sights as a co-witness or a backup. The Shadow Systems Multi-Footprint optic cut accepts a range of red dot sights directly so the Axio adapts to a duty loadout or a competition setup without an adapter plate. The black nitride finish on the slide resists corrosion and wear from daily carry and at 28 oz the Axio balances a steel chassis s durability with a manageable carry weight for duty and range use alike available for sale at GrabAGun.
