Hey, I've been looking at some used xd's as well as some new ones. I'm pretty much decided on a xd. But I was wondering if I would still be covered by the lifetime warranty if I got a used one. My concern is that if I pick up an earlier model, that I might have problems with the rust that some have had with the earlier models. If I picked up one of the used models, what's the probabilty of having SA redo it in the Armor Kote?
