Apilar,
excellent point indeed! i must admit though, i have not run into a single issue with a single valve knocker one of these yet. i am in no way discounting the idea, simply sharing my experience.
E-Luder & everyone:
i posted this above, but fear it was missed, so i'm posting lower, down here lol...
E-Luder:
thank you! i was clearly over-thinking the innerbarrel/outerbarrel rattle. leave it to me....
now that i am thinking of questions you may be able to help with, i have a few more for you if you don't mind.
1) are you able to VISIBLY IDENTIFY the difference between a stock and (let's just say) a GUARDER recoil or hammer spring? i ask because i have about 6 or so springs that i am unsure of the manufacturer of. some examples are below.
perhaps there is a test to see the tension? perhaps color or length (although almost all identical, i can see some SLIGHT variation, it could also be my aging eyes...)
2) have you ever found doubling up a recoil spring to be beneficial? this is simply out of curiosity.
3) have you ever fitted an aluminum BBH and consequent Piston Head from a G17 into the smaller G26 counterpart? this is something i have always pondered.
i appreciate this thread, and your efforts tremendously!

2 photos with slightly different lighting to see if there is a discernible difference in these springs........
