Guide rod spring on Ruger SR9

[erg33]

I have noticed other pistols like the 1911's or even some Glocks that when they go chamber a round (rack the slide) they can do it with very little resistance. It can be managed with even 2 fingers.

Can I assume they have a light spring on it or shall I start benching 500lbs?

Should I go to a lighter spring? If I do, could there be some issues I can face?

Any info will be appreciated.

It will wear in a little over time
