Fixing a frame lock

I am wondering if anyone knows what the general steps are for fixing a frame lock that is traveling past the tang of the blade. Reason I wonder is that I have a cqc-12 that is doing just that. I contacted the company and they said it could be fixed, but I am currious as to how. I suppose I could of asked them, but that might take a while. Thanks.
 
So , you are saying that the lock is not engaging onto the base of the blade to lock it ?
 
Easiest way is to bump the stop pin up in diameter to the next bigger size.

No, more so that it's engaging too far. Nearly to the point that the ball bearing on the Ti lock side is touching the g10 side. Seems almost like it (the tang, I guess) is over worn. Yet it still seems to lock up pretty solidly, so I wondering if I should even send it in and be without it untill it's fixed. I just can't invision how they would fixed this issue though. Perhaps it can be done by moving the stop pin up, or elongating the tang or the lock bar. I don't know. Just currious I guess. -Great knife by the way, has been through a lot.
Ahh, a bigger stop pin. Didn't think of that, thanks.
 
The larger stop pin is one way. Another also done by some is to take a round punch to the lock face at the bottom of the lock after breaking down the knife. Then stick the lock detent ball up on a hydraulic punch and let it hit with a specific force after heating up the lock contact area. Once done with just the right whack it will allow the titanium to squish out just enough metal toward the contact area that it allows the lock to catch just as it used to.

I don't particularly care for this method with liner locks let alone thicker frame locks but it has worked for some and I have done it on more than one occasion because it is the cheaper way to do it for those on a budget. What it does is create a very sticky lock that I simply don't much care for. The stop can do this also but one of the two ways should work. Don't get me wrong. The sticky lock can be dealt with and will even break in over time but its just near painful sometimes trying to close the lock once your finger gets tender because of it.

The other option of course is to simply replace the whole lock with a new one which I much prefer over trying to repair it. If given the option that is certainly the one I'd take.
