CCW spring rate change question

[operavoice]

I looked at Sonoma county's CCW pdf, and it says don't modify the gun AFTER certification.
Does this mean that trigger and hammer springs can be changed before certification?

For example, a Ruger SP 101 revolver, having a gunsmith install an 8 lp. trigger spring, and an 11 lb hammer spring, then use it to certify. (Anyone who has ever shot the SP knows why I'm asking about this specific revolver)

Seems pretty clear to me that it's allowable. If you're not sure, give them a call.

Bear in mind that if you certify with the mods, you'll be stuck with them if you don't like the way the gun handles.

Thank you for the response.
Other than needing better fitting moon clips, the gun handles vastly better with the slightly lighter springs. The OEM hammer spring hit so hard that it pierced a few primers, which, in my opinion made it dangerous, necessitating the change.
Now, it's solid indentations and easier to keep on target.

Pierced primers are no bueno. Happy to hear it worked out for you.

Just curious, but are you required to advise your IA if the gun is modded after you certify with it?

Based on the pdf, the gun would need to be recertified immediately after any modification, but I do not know.
I think letting them know beforehand would be the best policy for an initial cert. I have not applied yet, as I wanted to get a BSIS exposed cert first for career advancement.
The CCW application is next on my list of things to do.

Make sure it works flawlessly first. My SP101 had light strikes after changing springs. Never punctured primers, but the stock one was stiff. Got to be 100%.

Already tested it in single and double action.
Went with an 11# hammer spring instead of 10#, still hits hard and leaves deep depressions in the primers. I don't foresee any issues.
