Yeah, it’s a Klingon disruptor. Still not sure about its practicality of it or its visual connection to prior Klingon props, but divorced from its intended use it’s a cool design. Though I can kinda see the movie emitter style there, good point Scott.
I noticed in Vegas that these are largely FDM 3d printed - for example take a look at the striations on the grip that indicate that part was oriented on the print bed horizontally (laid flat).
First time I’ve seen a prop build that intentionally did not smooth out the print layers in some areas, and it’s an interesting effect to take advantage of those abstract contours when painting. By just hitting the edges of the layers, the grip ends up with something between a folded steel and metallic bone look to it (or coral! ).
Couple other things… the individual pieces are held together by black oxide button head cap screws, and there are clear parts that indicate internal lighting.
Here are some pics I took of the pistol and rifle in Vegas:
