OK, got it disassembled, and with the hammer out... I'm not quite sure how to get the trigger assembly out without completely fubaring the gun... updates as I go along!
EDIT: Got trigger and stuff out, and gave everything a good cleaning and lubing. I think what happened was a little gear sorta thing that moved the hammer block came loose. I think it came loose because the frame screws wern't as snug as I could have made them. Still headed to a range to find out... after a trip to walmart for some extra ammo and some targets... I'm outta shoot n' sees!
