From the behind the scene photo the way that the gun moves with the leg I assume the belt, holster, and leg padding are all attached together with some sort of clip
IronManic, I assumed the rendering is different from the actual one used but the only few clear shots I've seen of the holster...
it almost looks like a two part holster, a leather base (circled in red) that is sewn to the pants and the belt that has the clips coming down to attach to the leather base (circled in green).
thank you so much for that! sorry havent been on in a while been working on a tron baton project. the mods i plan on doing are add LED's, extend the barrel, replace the crappy foggy sight lenses and adjust the front handle between the barrel and saw blade because my hands keep getting stuck in...
had that same issue with my Gears costume had to get a cord to tie the cod piece up then the second issue i had was armor was wider than the bathroom doors
