Hey guys, looking for help with a broken spring on the lock for my .50 Muzzleloader.

Started with the hammer failing to stay back. So when I opened up the lock here is what I found...

Hoping guru's here may have some clues.

Thanks for looking !

Hello again, this is a CVA (Connecticut Valley ) .50 Black Powder type lock...
 
Just recently installed a new sear spring on my nearly 50 yr old CVA. There are two types a newer style and an older one.
I ordered from gun works muzzleloading emporium in Oregon.
It's a different place where you order online and they then call you to actually place an order. You can describe exactly what you need.
 
@wpage, Deer Creek Products would be the first place to look. You have a CVA Mountain Rifle. So, I took a look on the Deer Creek web site and the sear spring is listed as sold out. May be worth a call to some other suppliers. You will need to identify your lock for your rifle as being the CVA lock for the Mountain Rifle.

The Gun Emporium has the CVA/Traditions spring.

Thanks guys...
Deer creek was sold out. Gun emporium looks good waiting for the call back with shipping costs.
 
it looks to me like you also need a sear to me from your picture it looks bent. they do not last very long after you straighten them back out even if you heat and re temper do yourself a favor and just buy a new one

Maybe better to replace the lock entirely if the spring wont do the trick. See what your saying the edge looks curled up some. I may be able to file or stone it off.
 
@wpage, I think the trigger plate is much shorter on the Kentucky lock looking at pictures of the parts in the Deer Creek catalog. The Kentucky lock will not have the fly in the tumbler and may not have the bridle to support the tumbler in the lock. While the lock plate may fit, I don't think that option is a good replacement for the lock and trigger in your rifle.

Thanks for that...
Just put inquiry to see if they recommend it.

No you don’t need a new lock there’s no better lock made for your gun sears are cheap usually available on eBay I carry them when I’m at multiple day shoots
 
I also have a vintage CVA just like yours. Right under the main spring the lock plate is stamped Spain, see if yours is stamped also. Mine was given to me a number of years ago as it was in a basement fire. A restoration project is in order, mine has a nice birds eye maple stock. Bore is pitted pretty good though.
