So my M9 essentially got submerged in sand the other day and I had to take it apart completely to get it cleaned out. I was able to piece it all back together except for one piece.

It's some kind of tension wire but the exact placement I'm unsure of. When I dissasembled the gun it popped out.

If anyone could help me out with that's be great. The diagram in my manual doesn't help much. It just shows the piece hovering on the right side of the gun with no arrow pointing to where it goes. The only help I suppose is it tells me what the orientation of the piece should be, which I've used in the picture here.

Thanks in advance.
