Sci-Fi Long-stock Handcannon

Inspiration for this model came from AFI_ (https://www.artstation.com/artwork/1nzlZq) and their rendition of a revolver with a longer stock, and I wanted to add a Sci-Fi augment to the design in some way - this comes in the form of the speaker looking things near the barrel of the gun which would fire out tiny capsules/pods/ammo.
