If just the RF is out of alignment then you might be ok. In case the sensor is also off, you might end up shipping you camera twice...
Call them (Leica), and try to schedule a 1 week window of repair and sent it in for that week rather then sending it in it sits 3 or x number weeks in a bin with your name on it and gets repaired when they get to it. So you narrow down the time without your camera. Check with a local repair guy if they can do both RF AND sensor adjustment. My M9 sensor was off 20 microns, it could have happened during shipping or a bump (I bought it used). It needs to be positioned with 3 screws.
