This is an article from a local newspaper where Pat Squire of FIE was interviewed specifically about the SPAS and the how's and why's of it's popularity in Hollywood. Do yourself a favor and set aside five minutes to give it a good read.
Reading the image on the page is difficult, so it's recommended you grab the PDF from the download link on the page and enjoy it that way for ease of reading.
There's also another new little advertisement that was found recently that has been posted in the advertisements section, marked "The Ultimate Shotgun!" Who would disagree?
Thanks again to Tom S!
