Any competent gunsmith is able to get the recall replacement parts from Olin, and I am just on the other side of town from them.
Your main concern, aside from the safety issue, is to see about the accuracy situation.
The options that present themselves for that are numerous, from a bad scope or base system (loose or defective internal adjustment parts, some bases can be improperly assembled and cause problems with lack of solid mounting as well as screws loosening), crown wear uneven, bore condition with dirt or scars/throat erosion, bedding problems that cause twist or bowing, and more.
These type of guns are most likely being cleaned from the muzzle, so avoiding side contact or use of a pull-through is a plus.
If you contact anyone to have the recall fix done, make sure that they will perform just that, if you want, and not give you any song-n-dance about having to fix "safety-related but different issues" before doing the recall fix or with the recall fix. If there are any issues with other problems, you should have the option of having another shop to do the necessary fixes, and not be blackmailed into an "all or nothing" decision. If they provide a free estimate listing all of the problems, then OK. You can go somewhere else, if you want, without paying for anything more than the shipping both ways to the recall shop.
The Olin people provide money for a gunsmith to do the fix, and nobody should attempt to charge for anything else unless agreed upon in advance.
I might suggest a thorough disassembly and cleaning, along with the firing pin fix, but won't force the issue for these guns. I may refuse to work on any other gun that has an obvious safety issue if the safety-related work wasn't agreed as being necessary. Recall fixes can have a release signed by the customer stating that they realize the unsafe nature of the gun being accepted.
If anyone took their car into the dealer for a recall issue, you wouldn't want to be harassed into getting an exhaust system if they spotted a tiny leak. You also have the option of using a chain muffler store for that, not just the dealer.
