I've also had the factory FPs replaced with Bowen's FPs (by Bowen, and my local guy) on a .44 Special Flattop, a .44 Mag Flattop, and a .45 Colt Convertible Blackhawk.
Had C&S do the same thing on a new Smith N-Frame, the first thing I'd do on those to compensate for the dimensional changes they made with the progression of MIMs & locks.
Those Rugers HAVE to work, they're not range toys or hunting guns.
It may be a bandaid approach, but I see no harm in it, I was willing to spend the money to hedge my bets on all of them, it wasn't a big deal as far as the work itself goes, and I couldn't care less if the retaining pin ends are domed now instead of ground flush and contoured to the frame.
Whether you think it's worth the money or not is up to you.
The intermittent light strikes in Redhawks have been known for several years. It doesn't occur with every gun or every brand of ammunition, but it does occur.
Bowen considers the FPs too short, so does my longtime local guy, both are men whose opinions I listen to.
I take the guns mentioned above very seriously, and each one has had at least some minor modification to improve on how the factory sent 'em out.
Historically, if you return a problem gun to Ruger, I think you're just as likely to get a "It's within specs" response as you are to get any corrections made.
Hopefully I'm wrong.
This is not knocking Ruger, both of my Redhawks were deliberately chosen as primary bear defense guns in appropriate territory, and the decision was not made lightly.
Just a matter of making as absolutely certain they'll be there for me if needed as I can.
