The Maxim 9 integrally suppressed / silenced pistol is a new product of the American company Silencerco, previously known for their innovative sound suppressors / silencers for firearms. Maxim 9 pistol was conceived in 2012, and first prototypes were shown to the public in 2015. Mass production is scheduled to mid-2017.
Maxim 9 integrally suppressed / silenced pistol is a semi-automatic firearm that uses indigenous and patented delayed blowback system with separate breech-block being hidden inside a short slide. Opening delay is ensured by a special cam plate which is attached to the breech-block and upon early stages of recoil interacts with cam-shaped cuts in the stationary frame insert and movable slide. Pistol features a polymer frame with steel insert that hosts slide and breech-block rails, barrel bracket and trigger system. Barrel remains stationary when fired, dual return springs are located around two parallel guide rods, placed above the bore/breech face and inside the channels in the slide. Gun is striker-fired, with partial cocking achieved during the slide cycle and full cocking achieved by the pull of the trigger. Pistol is equipped with iron sights, and has an integrated mounting plate for micro red dot sights, located at the top of the suppressor body.
Integrated sound suppressor / silencer is of modular design; it has several expansion chambers with baffles, which are assembled using dual rods that run below the path of the bullet inside the suppressor body. Depending on the ammunition used, length of the suppressor can be adjusted by adding or removing front part of the suppressor / silencer, which is about 3 cm long. With front block installed, gun can effectively suppress even the supersonic 9mm ammunition. With front block removed, effective sound suppression / reduction is achieved only for subsonic ammunition, but the gun still would reliably function in this configuration with all types of 9mm ammunition.
