these are some guns ive been working on for a week or two. i’ve only been using blender for a 2 months so im still new but can you suggest anything i could do to make them better
also the arm on the right of the picture is not mine it is part of the “base male nude” file
Select the models and hit Ctrl+N then a menu pops up and you press Enter. Will sort out some of your shading issues 
Very good for two months of modeling btw
