Bear claw or Altman

[duramax55]

hi i have a 55 chevy 3100 with shaved handles with bear claw latches. I am having problem with the passenger door popping open to the safety when i hit a bump. had problem when i first tried to get them to latch properly and would pop easy. i then tried adjusting but no difference, so i bought a new set and put them in last fall and they worked fine. Now they started doing it again. i have a friend that is having the same problem. Dose anyone have any experience using Altman latches and are they better than the bear claw? i am done with the bear claw they are junk. when looking at the mechanism i can see that they bearly hook on so any little vibration and they pop.
