Just got a 930 SPX Blackwater edition had it apart to clean since it is having issues with low power loads that I am trying to remedy. However, I also noticed it has only the outer ring on the gas piston. Is this normal or is it also supposes to have the inner seal I have read about people mentioning? I noticed in the manual it points to a gas seal with an asterisk that states it is not included on all models (I am assuming they are referring to the inner seal).
