I have a P13.45 which I was shooting this weekend, and noticed that the rear sight had come slightly loose in the dovetail (I could move it about an eighth of an inch). My questions is: should I contact Para-Ord to send it back to them to fix, should I just have it fixed myself, or should I use the whole ordeal as an excuse to get night sights or some other type of aftermarket sights (and if so, which???)? I'm particularly weary of sending it to the factory because I think the factory is in Canada (I'd rather not deal with international shipping of a handgun).
