SilencerCo Maxim 9

It's not duty proven and, it's not even widely available, but this might be the coolest pistol ever. The Maxim 9 is an integrally suppressed 9mm pistol that uses widely available Glock magazines and sights, as well as being set up from the factory to accept red-dot optics. The suppressor is modular and can be shortened to allow a more compact package utilizing subsonic ammunition or kept full length for use with whatever ammo you want.
