Inspired by this concept created by Billy Machin to make a weapon similar to his.

The goal with this weapon is to keep those nice Machin silhouette and most of the form while also tweaking the functionality of the gun to better represent something mechanical or functional. This weapon while cool in concept doesn't seem to fit the human hand.
First Pass/ Blockout of the Weapon

Second pass of the weapon with tweaks in the form and a stronger focus on what a player would see in fist person.

Moved and tweaked the shapes of the holes to better fit the human hand.
Here is a quick paint over of what I think I the final color scheme will be.
As always feedback is welcome!!
Also please do not add random cables/forms. It`s always "Form follows function", no realistic/believable gun will have this exposed wirings (you can easily get stuck with them and cut them when moving the weapon in a firefight).
If you want wiring, integrate them into the weapon, cut some slides into the frame which the wires follow etc.
Will continue to teak and define shapes. Update soon.
Finished the weapon! made a few skins based on the original concept.
