You can't have no recoil under Newtonian physics.

You can have no perceived recoil, by either throwing something of equal mass in the opposite direction at the same time, having an open tube that doesn't restrict the propellant, or venting your propellant to push the weapon foward to balance the recoil pushing it back.
