While working on my N7 Armor costume I've also been developing a model kit I plan on building someday. All of the initial modeling is finished and the pieces are separated. Now all I need to do is go in and hollow out each part and combine the dynamesh objects together for printing.

Great work, I look forward to seeing it printed! I used game data to machine one a few weeks back, lacking most of the detail. One thing I did notice, which you might want to think about before you get it printed, is on the back of the grip section - where the grip widens at the top rear can be a bit uncomfortable in the hand. It kinda digs in around the webbing between your thumb and forefinger. Could be worth softening it perhaps, I know I will be on mine!
the hard edges near the barrel look too hard though imo
some more curves would do wonders
