You dont know what you dont know (since I did not read any manual or advice before hand). haha.. Hopefully your issue is just as simple.
There is no need to put any oil in the firing pin channel of any semi-auto.
After removing the firing pin and cleaning the channel. simply wipe the firing lightly with a cloth with a drop or two of oil on it.
Oil collects dirt and that dirt will eventually gum up the firing pin.
I'd pull the Security 9 apart and re clean the channel before I'd send it back to Ruger.
Firing pin chanels do get dirty and an owner needs to now how to clean them or make friends with a local gunsmith.
At some point in time it will get so dirty it needs to be maintained. A trip to the factory just for that isn't necessary.
Now, if you are sure it is clean and not full of oil, that your primers on the ammo you use are seated and not hard, then Ruger will help.
