I had a P226 magazine that was loaded with HydraShoks sometimes toward the end of the Hurricane Andrew recovery phase that I finally tried a year or two ago. The magazine and ammunition was fine. That said I would try to shoot ammunition I carry every year or two just to be cautious. I have a vague concern about ammuntion carried in a gun deteriorating from either lubricant or moisture. And I try to not cycle rounds into and out of the chamber too much to try to avoid the bullet being set further into the case than it should as that may cause pressure to rise.
I never talked to anyone who had to fire their gun who said "I wished I had the smaller gun and fewer rounds with me" Just because you find a hundred people who agree with you on the internet does not mean you're right.
