Mine is still not fully reliable after a complete overhaul. I took it apart and degreased and cleaned every single part. I smoothed some of the rough production edges. I replaced all of the eight springs and got some original NOS magazines. Now it works most of the time but I still wouldn't rely on it as a carry gun.
Yet I do have to say in the HSc's defense that it's out of the box reliability is still above the average small cal. pocket pistols of that vintage.
