Sig P226 Problem.

[Duckbay]

I think he means the return spring that closes the cylinder as the action cycles.

Thanks for the help folks.
Think this is the issue as the wider spring inside the cylinder was twisted as it could be seen through the square aperture on top of the cylinder. The other spring must be the return spring to pull the cylinder back which had come free but no idea where it goes. Found the schematics online but really cannot make any sense of it.
