This here is a replica of the famous Blade Runner pistol (it had a cameo in Fallout New Vegas). It took 30 hrs over 6 years for creator Adam Savage to build, which isn’t that bad considering he has been pretty busy with Mysthbusters (yep that one). It has parts from all kinds of weapons and custom milled steel and aluminum frame and strong resin components. This thing is pretty spot on, even if a little too small. If there is something I enjoy, its movie memorabilia(particularly leeloos thong).
