FOV screenshots in Source

I recently finished Half-Life: Source, and after doing so, I had the mind to check here to see if there were any interesting nuggets of information to be found... only to find that, much like the game itself, the page was fairly barebones! I couldn't really think of any fixes or whatnot to be posted, but I thought I could easily update stuff like Game Data, Save Game Cloud Syncing, Borderless Fullscreen Windowed, etc. So shadowing my edits to align with the way the Portal and Half-Life 2 pages are done, that's what I did (I neglected to leave summary notes, though :(). And then I got to FOV screenshots...

With my life story out of the way, here's my question to you: How did you capture FOV screenshots for Half-Life 2 without capturing a few pixels worth of movement from Gordon's gun? Is there a command to call in the dev console that stops weapon animations or something? Noob question maybe, but I couldn't find anything in my Googling or Ctrl+F'ing in the Console Command List on Valve's wiki.
