These are the actual guns were used in the movie The Departed (2006)! They are part of the upcoming Nation Firearm Museum Hollywood Guns exhibit. The latest episode of The Curator’s Corner discusses these guns and how they were modified to work with blanks (Click on “program Archive” button, then click the Mar 25 tab, then scroll down to “Curator’s Corner” … yes, they do know it is hard to link to them and are working on it!). Many thanks to Lars for emailing them me the photos.
He has blogged about them at NRABlog.Related
