I want to add another reply to the thought that you can't or shouldn't be able to move the lock across. Well, you can actually do this on a great deal of frame locks but on many it is more difficult and on some extremely hard to do that and even harder to close once you do because it can cause them to stick once you force the lock in further. However, with that said I think anyone that has owned a Leek, or Storm or some other frame lock by Kershaw with the 'flatter' contact area that you are surely aware that they do allow you to snap the lock out there easy enough to place it behind the blade better and you can push the lock in and get it to seat and then close it quite easily. My Chive and all four of my Leeks are the same way in this regard.
On all but one of these Leeks the locks are hardened stainless so there is very little concern for excess wear from doing this but this will slow down the break in also since stainless does in fact wear slower than titanium. To the original starter of this thread, if a magnet sticks to your frame its a stainless lock so you may be waiting a while to see the lock move in more rather than see it happen sooner. I'd just keep moving the lock out like you did in that one picture, I think it was the second one, and do this when you know you want or need more support for the blade. If yours is like all of mine I doubt its any harder to close the lock after doing this or if so not enough to be of consequence.
In my opinion this is typical of Kershaw Leeks when new and is not call for mailing it to customer service.
