I found The Target Shoots First! All my various finding-rare-movies resources had failed me, but today I found it... on Erica's living room coffeetable! We were packing up her house today and she said held up a hand-labeled video and tape and asked, "hey, what was the name of that movie you were looking for?"
Her friend Rick had given her a copy for her birthday and it had gotten buried on the coffeetable. And then we got cast in Doc South and I started going documentary-crazy.
The coffeetable! Ridiculous.
