I would find a source for the lock's main spring,
Just a heads up for those that may not know (I know Jonathan does),
Deer Creek Products of Waldron Ind.
765:525:6181Is and has been CVA's custom shop for decades. Rumor flying out there is they bought all of CVA's stuff when CVA closed traditional guns but that's really not the case, they have direct market with the Spanish suppliers for the CVA as well as Traditions arms and other Spanish made guns.
An excellent and knowledgeable Mom-n-Pop's type shop that has a lot of stuff.
No web site, it's phone and fax only but costs are appropriate to our pastime.
By the way they are the folks that bought the legendary Douglas barrel machines, also decades ago. And still run them making barrel replacements here in the USA.
p.s. I've always wondered,, How long does Deer Creek have to own those machines before they stop being Douglas machines and become Deer Creek machines?
