A hair clip would look silly in a rifle, or loading clips. They’d probably want magazines though heh.
Well it could have been a Garand loaded with a clip or a Mauser rifle loaded with a stripper clip, or an 1896 Mauser pistol or a Steyr-Hahn tho both the Mauser and Steyr had late models which used magazines.
The Italian Carcano which got Kennedy used an enbloc clip which worked similarly to the Garand except it held less.
I think they’d look silly with a rifle and a Ladies Home Journal or Cosmopolitan magazine, too. Playboy magazine, not so much.
Back in my day in military training they were called clips.
