The Maxim 9S uses a monolithic, integrally suppressed upper with removable baffles and rod sets, allowing the user to configure length. In the short layout shown here, overall length is 9.54 inches and weight is approximately 37 ounces. The front cap carries the SilencerCo "X" emblem, and twin cap screws secure the muzzle end.
Its operating system is striker-fired with multiple passive safeties, including a trigger safety, firing pin block, and sear safety. A flat-faced trigger, bilateral slide stop/release levers, and rear slide serrations round out the controls. The polymer frame has a textured grip for consistent handling.
Tall, integral fixed sights are mounted to the upper and consist of a prominent front post and a square-notch rear. The underside of the suppressor housing includes KeyMod accessory slots for mounting compatible accessories.
Chambered in 9mm Luger with a 1:10 twist, the Maxim 9S is compatible with Glock 17-pattern magazines and has a 17+1 maximum capacity. Factory literature notes hearing-safe operation in the short configuration with subsonic 147-grain ammunition, and in the long configuration with common 9mm loads.
