    Sorry, what is the barrel hood? The top of the chamber when it is in battery???
     
  4. its the very top of the barrel as seen when the slide is closed.

    My sig barely moves when I push it down, but my almost new glock 21 moves like crazy. Is that bad????
     
  6. it's normal for the barrel to move some when the gun is not cocked.

    Describe "like crazy". Is it a factory barrel? Any modifications to the gun? How old is the gun?

    All factory. Brand new. I shot great with it. I figured out though, if I hold the slide in place so it doesn't move back at all then the barrel chamber won't move around at all. So I think it was just the slide going back a very tiny bit and allowing the barrel to move.
     
  9. yea i think we got to the bottom of that mystery on the phone

    But my main concern was the sig. As the slide is locked back, I can move the barrel back forth up down in out and even twist it a little. it just seems like it is allowed to move too much. Don't know for sure though. An the guide rod also can be moved a lot while the slide is locked back. Wish I could post a video.

    While the slide is locked back? Of course there's going to be movement, because the action isn't locked.
