Your modeling and texturing skills…… a very guwd! Especially well done with the normal map it came out so good. As for personalizing the gun, changing the dot sight color, addons, or just a small engraving and as mentioned by John and Silent contrast with materials, color, ect. Ya know logos, camo or something like that. Really depends on the personality of the person that would be wielding the weapon to determine how it will look.
