The PPG is the sidearm used by B5 security on the Bablyon-5 TV show. I've tried to get the scale as accurate as I can, although it may need to be scaled down for cosplayers with smaller hands. The original prop was made from machined aluminum so getting the finish to read right is a big part of making it look good.

Note: The image from TV and the basic design are copyrighted by others. My 3D model is a totally original creation inspired by their ideas.

A nice modification would be for the "cap" and "body" to install magnets so they could snap together like they do on the show.
