I was just going to reinstall the lock on my Pendersoli Charleville and noticed a flaw in the main spring right at a point I would think is a high stress area. I think it’s a flaw; regardless I think it may break. I’m going to order a new one which I hope someone has in stock. I bought it from Dixie so I’ll start there. Anyway I’m going to try to polish it out until I can no longer see the crack in the spring. I don’t think it’s a stress crack I would think it would have already cracked being these spring are so hard. It’s obviously needs attention?

Personally, I would try using a round carbide file or small rotary stone in a Dremel tool to get rid of the nick or crack and then polish with cratex abrasive "points" to get it real smooth. That MIGHT do the job alone. However, if the "nick or crack" reappears, then the spring is shot and will need to be replaced.

I just sent an email to Pedersoli asking for the PN of the spring. I called that 800 number I found on a similar thread they need a PN to insure fit. Can’t argue with that. Once the order is placed takes 60 to 90 days LoL. Things are really upside down nowadays.
I will do that need to order up some cratex. I’m hoping it’s just cosmetic I never noticed it before though it looks like it’s been there all along.

Spring Steel is like glass, that little crack is like a chip in your windshield….it’s gonna spread, just a matter of when.

Dang! Hopefully polishing it below whatever it is defect crack or nick will buy me some time.who has 60 to 90 days to wait for a replacement.

These things are sometimes cast, not machined or forged. It will need to be replaced. Good luck.

If you grind that surface flat and take out the groove, you should eliminate a break. Just make sure you polish out what you grind so it ends up smooth. There is more than enough material there to do that and have what is needed after the fix. Some springs can be trimmed with a file. I would check a file first, as for me it is easier to control the amount of removal. Secondly find where you can get a back up spring in case you ever do need one.

Funny I placed an order for that polish kit Gus recommended Brownell has one $20 some odd dollars i order that and small diameter grinding stones. I’m a customer so I log in get through check out but it doesn’t like my cc is not the ship to address. I call the customer service number and a recording comes on telling me I’m number 221 and the weight time is something ridiculous 😝 . So if you like press one and we will automatically call you back at this number 😆. I’ll try the website again tomorrow with my debit card if my wife leaves me with something. Worse wait then trying to get a time to play Bethpage Black so many years ago after the first US Open there. Business is good at Brownells
 
If you take a close look at the pics it looks like that is more of a cut than a crack , why I think this is because the metal around the cut appeared to have been displaced . ie: it bulges a little , it also is v shaped and tapered . . I'd get a new one then grind out the damage on the old one and keep it as a spare .
The first time used my Charleville I cleaned the lock with some gun scrubber spray , which dramatically reduces the temperature of the metal , I opened the frizzen and the feather spring ( frizzen) went ping /SNAP . Luckily I was able to get a new one fairly quickly , Moral of the story is never use spray cleaner an a spring and if you do wait until it reaches room temp before working it .
I softened the broken spring , filed it down to make an awl then re hardened the tip and gave it an antler handle , so all was not lost .
 
Just looks like a nick to me.
Yes it does appear to be just a "nick". I'd file/polish it out and put the worry to sleep....at least temporarily.
You can call it a ‘nick’ if you like, but ultimately it is a ‘stress riser’. The spring will eventually fail, and with a ‘nick’ as shown by the OP, guess where the spring will fail 99 out of a 100 times? Either get a replacement spring or grind/polish that defect out. Ignore it and spring will fail at most inconvenient time, guaranteed by rules of nature.

Hello, you have to start knowing the code of the main spring, looking at the parts' diagram you can find in Pedersoli's website where the gun is featured, Chaleville's main spring has the code 0800003703, DGW may have the parts in stock, another representative carrying parts is V.T.I www.vtigunparts.com, using the same part's code and finally Pedersoli has an online shop where it is possible to purchase parts and accessories, delivery time 2 or 3 days from the order https://shop.davide-pedersoli.com/en/

While it is not historically correct I suggest you polish it as is , and fill the cut with J B weld and sand it smooth.
 
That looks like a cut rather than a crack. Even so, it's a stress riser in a stressed area. It could let go on the next shoot but it could also last a very long time
