Hey Charles, if you just got the 7505, keep playing with that stop pin adjustment. I messed with mine over a few days and I think that the combo of the lockbar breaking in and finally getting the stop pin in a good position solved my vertical play. I was a little peeved too with mine too, especially considering that sending an automatic in is not as simple with Benchmade. Now it seems to be holding, kind of late lockup, but similar to my 755's.
