Hmmm...the "bolt action" locking system was designed by Blackie Collins and as far as I know, the blade should be secure when locked. I'm not sure what you mean when you say it can be pulled out when in the "correct" position. Only you can determine whether it's safe, and that only by your own personal testing. The older Gerbers were quite good and used very good blade steel. If the knife is in great condition and is not operating properly, you might want to contact Gerber, tell them the problem and see if they'll fix it. I wish they still made these (and others not currently in production), but they're putting out a lot of junk these days.
