Wolff says stock J Smith mainspring is 8.5 lbs, they also offer 8 and 9. My 640 is good with an 8 and a lighter rebound spring, but it also got the action parts honed to reduce friction in proportion to spring load reduction. My box stock M38 needs the stock spring.
Or you could hit Smith up for a call tag and label to ship on their account for a warranty claim.
Edited, I see they have done that.
