on the hanlde of the mac10 go in and delete the polygon around the bump then use create to make new faces. or you might get luck and only need to draw and edge from the top corner where the fold is happening to another edge where the handle is extruded from. if that isn't clear let me know and i'll try to rephrase it.
aye, i hate it when those things crop up...oh well
pretty good other wise, nice to see the uzi with the correct labeling too
except for the shading i see no errors, that i can think of...wait is that another shading error on the grip at the front of the mini-uzi? or is it just my eyes :x
