Personal meetings for transferring restricted guns are discouraged it you don't know the person. Do you know that he has a PAL? If you still want to do it, get all his personal details including copy of PAL before you meet up. CFC is closed on weekends and holidays, a transfer of restricted cannot be done on the phone, even AB takes at least one day, many times even even 2.
If you are transferring a long gun, things look a bit different, but I cannot tell you how many times I have met up with somebody and then the person didn't buy it in the end, usually a waste of time.
