Mass Effect M3 Predator Pistol in two parts

The original was too big for my printer, but at 75% it was too small for my hand. Sadly, neither the original or its original posted anything but STLs (why don't more people post reasonably-editable source?) and importing an STL this complex and cleaning it up takes HOURS and produces some incredibly bulky files. But RepG didn't complain when it sliced the results, so I think it should be printable, despite some artifacts of the process.
Note, the .skp files still reflect the 75% scale-down.
