The nice lady in the Warranty Dept. was wrong when she stated the OD-1 was defective (if that is what she said), because the lock bar could be pushed over to the far right. (Oh man, just another thing for 3G to jump on us for)
The OD-1 is a bit of a slippery slope when it come to lock up vs. action. We prioritized the action so the lock tension in minimal. Should we put too much lock tension, you would never be able to flip the knife open, ever. As long as there is no play when in the open position, I'm unsure what the problem is.
We are working some new internal geometry and some thicker spacers to improve on this, although IMO, the results will be minimal lock tension gain.
We've done internal tests on the solidness of the OD-1 frame lock, and have concluded that the lock is reliable and safe. Just remember that not all frame locks are the same, and the Overdrive mechanism on the OD-1 puts it in a class by itself.
Here is the thread yerscattergun is referring to, and it addresses frame locks in general:

Still don't feel you got jumped on "pretty hard", but what the heck do I know...
