This was Concept/Commission #12
Concept was for a Massive double barreled Pistol firing what is in essence a Miniaturized WH40K bolt like projectile (may upload that detail & cut away image later).
Though I'm quite proud of some parts of this image, some of it still irks me and I'll probably be nitpicking on parts into infinity. Projectile is 21x60mm Gyrojet round with a cartridge based Kicker/Ignitor/Unseating charge.
