I did shoot a roll using my handheld light meter this past weekend. I just developed it today and everything looks great. So, it's definitely the light meter. I tried changing the battery again since I now have like seven of them kicking around in both silver-oxide and alkaline, but still no good. I'll look into getting a new meter at some point. For now it's handheld all the way! I'll try and post some shots soon.
Thanks everyone for your help,
