The black Q Erect9R is the same fully modular 9mm silencer as the original, finished in black nitride (Q part no. SIL-E-9-BLACK). Removable baffle sections let you add or take away length, weight and sound reduction depending on your host, ammunition and use. Q says it stays roughly as light as a smartphone fully assembled, and a booster assembly is included for compatible tilt-barrel pistols. It is a one-can answer for 9mm pistols and carbines.
