I'm looking to cosplay 2013 Lara Croft, and am trying to get a fake handgun as one of my props. I can't seem to find a simple prop in the design I'm looking for, but I have found airsoft guns that look about right. I know about keeping the orange tip on it, and I know that it wouldn't have anything loaded, but how exactly would one disable it from firing completely? The ACen rules stated, "Gun-like props also must have their firing mechanisms disabled," but I'm not fully sure how to do that. Can anyone give me some tips?
